2. Enter the required values or replace existing entries.

   All fields, line commands and special PF keys provided on the screen are explained in the following section.

This section covers the following topics:

- Fields: Network Schedule Definition

- Line Commands: Network Schedule Definition

- Special PF Keys: Network Schedule Definition

### Fields: Network Schedule Definition

The input fields on the Network Schedule Definition screen are described in the following table:

Field | Description
--- | ---
Schedule Owner | Owner of the schedule to be used. Wildcard selection is possible. Default: Owner of the network
Schedule | Name of the schedule to be used. Schedule comprises a link to a calendar. Definition of dates on which the network is to be executed.
effective from | Schedule effective from (date and time) If a schedule should not become effective immediately, enter the date (and time) of the validity begin here. If no time is specified, the schedule becomes effective at 00:00.
effective to | Schedule effective until (date and time) If a schedule should be used only until a defined date, enter the date of the validity end here. If this field is empty, the schedule will be used infinitely many times in the future. (Default) If no time is specified, the schedule remains valid until 23:59.
Cmd | Input field for line commands: see Line Commands: Network Schedule Definition.
Schedule Dependency | This option is used to specify days when the network is deactivated and not executed. See Adding and Modifying a Time Frame Definition.
Earliest Start | Earliest start time for the network. No job in the network can start before this time. The Earliest Start time is used to compute network schedule times. See also Date and Time Formats (section Using Entire Operations) and Processing of Time Frame Definitions. For further information, see also Defining Multiple Network Activations.
Latest Start | Latest start time for the network. The first job in the network must start by this time, if possible. If not, a warning message is sentl, and the job is not submitted. See also Date and Time Formats (section Using Entire Operations) and Processing of Time Frame Definitions. You can specify the number of workdays or calendar days to be used for later starts: see Days later below. For further information, see also Defining Multiple Network Activations.
Deadline | Time by which the last job in the network must be finished. The deadline is used to compute the earliest and latest start times for the jobs in the network. See also Date and Time Formats (section Using Entire Operations) and Processing of Time Frame Definitions. For further information, see also Defining Multiple Network Activations.
Days later | This field is to be used if Latest Start and/or Deadline are later than 24 hours after the Earliest Start. Valid values: 1 - 999 days. Default for Deadline: 2 calendar days later. See also Processing of Time Frame Definitions. Note The Entire Operation default settings provide the option to define later start times in units of hours instead of integer days, for time ranges that are not a multiple of 24.
T | Specifies the day type:
`C` | Calendar day (default).
`W` | Workday as defined in the calendar linked to the schedule.
Number of Activations | This field is used to activate a network more than once a day. In this case, enter the number of activations per day. If the network is to be activated once per schedule day only, leave this field blank. Valid input values: `2` to `999` If a non-zero value is specified here, a time interval (every … minutes) must be specified, too. For further information, see also Defining Multiple Network Activations.
every ... minutes: If a network is to be activated more than once per day, you can enter the time interval between two subsequent network activations. This field can be used without Number of Activations, too. In this case, the number of activations will be limited by the defined latest network start time. Unit: minutes See also Defining Multiple Network Activations for further information.
or activate at | In these fields, you can enter up to 10 activation times, as an alternative to Number of Activations. Format: HH:MM or HHMM or HH Examples: `20:11`, `1314`, `18` Note If activation times are defined for a network, the job-specific time frames will be adapted to fit into the network time frame. See also Defining Multiple Network Activations for further information.
Day Deadline | If a Day Deadline is defined, the Deadline of multiple activations (every … minutes or Activate at) is limited to this time on the day of the activation. If multiple days are needed for a perodic activation, the activations will be continued at the defined Earliest Start on the next day. Format: HH:MM For further information, see also Defining Multiple Network Activations.

### Line Commands: Network Schedule Definition

The line commands available for the time frame columns on the Network Schedule Definition screen are described in the following table:

Line Command | Description
--- | ---
`D` | Delete the time frame definition. See also Deleting Time Frame Definitions for a Network.
`I` | Insert an empty line before the current line.
`M` | Add or modify the schedule dependency of the time frame definition. See also Adding and Modifying a Time Frame Definition.

### Special PF Keys: Network Schedule Definition

You can perform the following function from the Network Schedule Definition screen using these PF keys:

PF Key | Name | Function
--- | --- | ---
PF4 | ExplD | Explicit Date. Define explicit execution dates at the network level. See also Defining Explicit Dates for a Single Network only and Date and Time Formats.
PF7 | Sch.L | Schedule list. Display the linked schedule in a half-year calendar format.
PF8 | Sch.M | Schedule modification. Invoke the schedule definition of the defined schedule.
PF9 | Delete | Delete (reset) all fields of the screen.

## Processing of Time Frame Definitions

This section describes the rules and processes that apply when specifying time frames for a network or job schedule on the Network Schedule Definition screen or the Scheduling Parameters window of a job master or job active:

- Hierarchical Order

- Changes to Time Frames of Active Jobs

- Time Frame Selection Rules for a Network

- Time Frame Rules for Start/End Times and Day Later Definitions

### Hierarchical Order

Time frames defined on the job level override time frame definitions made on the network level for this job. If no time frames are defined here, the job network defaults apply.

### Changes to Time Frames of Active Jobs

All modifications to time frames of an active job affect the active database and the current job run only. Time frame definitions for the job master remain unchanged.

### Time Frame Selection Rules for a Network

Time frames are selected according to the following rules:

- A blank line with no time frame dependency entry is applied as the network start date if no other time frame dependency entry matches the network start date.

- From top to bottom, each line with a defined schedule dependency condition is applied to the network. If a condition is satisfied, the respective time frame values are used for the active network.

  Example: The definition `+CW+3` means this definition applies if the network starts on Wednesday. `-CW+3` means this definition applies if the network starts on all other weekdays except Wednesday.

- If none of the defined lines is selected, the network uses the default time settings. See also Default Setting (2) in the Administration documentation.

### Time Frame Rules for Start/End Times and Day Later Definitions

- If both Latest Start or Deadline and Days later are not specified, the Entire Operation defaults specified for Default Latest Start after Earliest Start and Default Deadline after Earliest Start on the Default Setting (2) screen apply (see the Administration documentation).

- If Latest Start or Deadline is given and Days later is not specified, Days later is automatically filled as described above.

- If applying any of the above rules and Days later of Latest Start or Deadline becomes greater than 999, it remains empty and an error message is issued.

- If Latest Start is before Earliest Start and Days later is not specified, the Days later value for Latest Start is set to 1 by default.

- If Deadline is before Earliest Start and Days later is not specified, Days later is set to `1` so that this time follows the earliest start time.

## Defining and Deleting Time Frames for a Network

- Deleting Time Frame Definitions for a Network

### Adding and Modifying a Time Frame Definition

To add or modify a time frame definition for a network

1. If you want to create or modify a time frame definition, enter or replace the required values in the time frame columns on the Network Schedule Definition screen.

   For valid input values, see Fields: Network Schedule Definition.

   For valid time formats, see Date and Time Formats in the section Using Entire Operations.

   See also Time Frame Selection Rules for a Network and Processing of Time Frame Definitions.

2. If you want to add or modify the schedule dependency for a time frame, type `M` in the Cmd column next to the line that contains the required time frame.

   A Schedule Dependency Definition for Time Frame window like the example below opens:

       +---------------------------------------------------------------+
       |                                                               |

       +---------------------------------------------------------------+

   The input fields contained in the window are described in Fields: Schedule Dependency Definition.

### Deleting Time Frame Definitions for a Network

To delete a single time frame definition

1. On the Network Schedule Definition screen, type `D` in the Cmd column next to the time frame definition you want to delete.

   A confirmation window opens.

2. Enter `Y` (Yes) to confirm the deletion. `N` (No) cancels the action. Press ENTER.

   The selected time frame definition is removed from the Network Schedule Definition screen.

To delete all time frame definitions

1. On the Network Schedule Definition screen, choose PF9 (Delete).

   A confirmation window opens.

2. Enter `Y` (Yes) to confirm the deletion. `N` (No) cancels the action.

   Press ENTER.

   All time frame definitions are removed from the Network Schedule Definition screen.

To delete a time frame dependency from a time frame definition

1. In the Schedule Dependency Definition for Time Frame window, choose PF9 (Delete).

   A confirmation window opens.

2. Enter `Y` (Yes) to confirm the deletion. `N` (No) cancels the action.

   Press ENTER.

   The time frame dependency is removed from the time frame definition on the Network Schedule Definition screen.

## Defining Dates for Explicit Network Execution

You can define explicit dates on which a network always or never executes, regardless of any other schedule definitions. Explicit dates supersede all other schedule definitions.

You can define explicit dates for all networks linked to a schedule or for a single network only.

This section covers the following topics:

- Defining Explicit Dates for a Schedule

- Defining Explicit Dates for a Single Network only

### Defining Explicit Dates for a Schedule

To add or modify explicit dates for a schedule

- On the Schedule Definition screen, enter the required dates in the input lines under Explicit Dates as shown in the example of a Schedule Definition screen.

  For valid input values, see the field Explicit Dates in Fields: Schedule Definition.

### Defining Explicit Dates for a Single Network only

You can define explicit schedule dates on the network level. Dates defined here are network-specific in contrast to schedule definitions which affect all linked networks.

Notes:

1. Any modification made with this function causes the recalculation of the current schedule of the network.
2. Explicit dates override all definitions made in schedule(s) linked to the network.
3. Deletions of planned activations can cause that the day of deletion is added to the dates to be excluded on the Explicit Dates screen (for example, `29.01.19-`). This is to avoid that the network is again activated on this day. (Explicit exclusion dates on the network level are set implicitly by the network activation cancelling function.)

To define explicit dates for a single network only

1. Choose PF4 (ExplD) on the Network Schedule Definition screen.

   A Network Schedule - Explicit Dates screen like the example below appears:

        26.02.10                ***** Entire Operations *****                12:52:05

        Owner TESTBED         Network Schedule - Explicit Dates     Network NET01-517

       -------------------------------------------------------------------------------

        Explicit Dates:

         27.02.10-  28.02.10-  01.03.10-  03.03.10-  _________  _________  _________

         _________  _________  _________  _________  _________  _________  _________

         _________  _________  _________  _________  _________  _________  _________

         _________  _________  _________  _________  _________  _________  _________

       Enter-PF1---PF2---PF3---PF4---PF5---PF6---PF7---PF8---PF9---PF10--PF11--PF12---

             Help        End         Save                    Reset

   Enter or replace the dates you want to explicitly use for the selected network. The input fields and special PF key are described in the following section.

2. Choose PF3 (End) to return to the Network Schedule Definition screen.

#### Special PF Keys: Network Schedule – Explicit Dates

You can perform the following function from the Network Schedule - Explicit Dates screen using this PF key:

PF Key | Name | Function
--- | --- | ---
PF9 | Reset | Reset (delete) all definitions.

#### Fields: Network Schedule – Explicit Dates

The input fields of the Network Schedule - Explicit Dates screen are described in the following table:

Field | Description
--- | ---
Explicit Dates | A list of explicit dates in the date format specified within Entire Operations defaults. If the date is followed by a minus sign (`-`), the date will be excluded from the schedule. Example: `21.12.16-` The network is not activated on 21.12.2016.

## Defining Multiple Network Activations

You can repeat network activations multiple times.

Note
If activation times are defined for a network, the job-specific time frames will be adapted to fit into the network time frame.

To define multiple network activations

1. On the Network Schedule Definition screen, enter (or replace) either or both of the following:

   - In the Number of Activations field, enter the required number of activations.

   - In the every ... minutes field, enter the time interval to be used for activation.

   Or:
   On the Network Schedule Definition screen, enter the following:

   - In the input fields next to or activate at, enter single or multiple times to be used for network activation.

2. If required, enter a time limit for activation in the Day Deadline.

3. Choose PF5 (Save) to save your entries.

The rules that apply when defining multiple activations are described in the following section:

- Activation End

- Calculation of Time Frames for Multiple Activations

### Activation End

Multiple activations are limited by

- the defined number of activations, if greater than zero. The defined latest start and the defined deadline have no effect on this.

- the end of the schedule day,

- the latest start,

whichever applies first.

### Calculation of Time Frames for Multiple Activations

The following applies if both Number of Activations (`na`) and every ... minutes (`em`) have a non-zero value:

- The latest start time of a time frame (`tf_latest_start`) is interpreted as the latest start time of the first multiple activation.

- For activation `1 <= n <= na,` the latest start time of the specific activation will be set to `tf_latest_start + (n - 1) * em` .

- The multiple activation end time (`mae`) will be calculated as `mae = schedule_date + tf_latest_start + (na * em`)

If the multiple activation end time (`mae`) is after the defined deadline of a time frame, it will be set to the deadline of the time frame.

If the multiple activation end time (`mae`) is after the end of the schedule day, it will be set to the end of the schedule day.

Note
A network is no longer treated as "already activated on the current day" if there was a multiple activation on the day before, which resulted in some runs that were executed after midnight. In this case, automatic activations (due to schedule) will not be blocked by the "activation on current day" check.

## Viewing a Network Schedule Definition as a Calendar

To display the calendar view of a network schedule

1. On the Network Maintenance screen, type `W` in the line command field of the selected network. Press ENTER.

   A Network Schedule screen like the example below appears:

   The current half of the year in displayed in the calendar format. The dates on which the network is to be activated appear on the schedule.

   The network based on this schedule is activated every weekday from January to June except on Saturday and Sunday.

   You can enter any valid year in the Year field in the header section of the screen to display the schedule for the specified year.

   If a calendar is linked to the schedule but not defined for the displayed year, you are notified by an error message.

Note
There are two different formats for all schedule and calendar displays. The format can be modified in the Default Setting (1) option of the Entire Operations Defaults described in the Administration documentation.

## Producing a Network Start Summary

This section describes how to produce a network start summary for a single network. The report looks like the example of a Network Start Summary shown in the Reporting section.

If you want to produce a Network Start Summary for all network activations on a given day, see the corresponding report described in the section Reporting.

To produce a network start summary for the current network

1. On the Network Schedule screen, select a valid date and choose PF4 (Overv). In a z/OS environment, you can place the cursor on the required date.

## Schedule Modification and Planned Starts

In the Entire Operations Defaults, the system administrator can define that network schedules are to be extracted several days before the network starts. These planned starts are represented by activation trigger records, which already have a run number.

If your schedule modification affects any planned start, you have the option of cancelling the starts or keeping them active. The following window opens:

### Cancelling (Deactivating) a Planned Network Start

You can cancel (deactivate) a planned network start only if a run number has already been assigned to the network. Jobs already activated for this run will be deactivated.

A planned network start without a run number can be removed by modifying the network schedule definition or the schedule linked to the network schedule definition.

If an activation is removed for a scheduled date, the date is excluded from the network schedule definition (explicit dates) to prevent further activations for that date.

### Symbol Prompting for Network Starts

If a run number is assigned to a network planned to start (be activated), you can perform symbol prompting.

To perform symbol prompting for a planned network start

1. In a Next scheduled Network Starts window, enter `S` in the line command field of the appropriate job or network with Type = `Aw. Symbol Prompting`.

2. Press ENTER.

3. A Symbol Prompting for Table screen appears.

For further information, see Symbol Prompting during Network or Job Activation in the section Symbol Table and Symbol Maintenance.

### Listing and Modifying Active Symbol Tables

To list and modify active symbols in the active symbol table of a network

1. In the Next Start Times window, enter `S` in the line command field of the appropriate job or network with Type = `Schedule, active`.

2. Press ENTER.

3. A Symbol Tables (active) window like the example below opens:

## Displaying Next Network Starts - System-Wide

Scheduled starts are extracted from the network schedules and put into a pre-activation status. The extraction is usually performed at midnight, one day in advance.

Manual starts are explicitly invoked as manual activations by any user. If a special start time was not entered, the daily time frame is used. See Activating a Job Network Manually in the section Network Maintenance.

This section covers the following topics:

- Next Planned Network Starts

- Columns: Next Scheduled Network Starts

- Modifying Planned Network Start Times

### Next Planned Network Starts

To display a system-wide list of all planned job and network starts

Column | Description
--- | ---
C | One-character input field for line commands: see Line Commands: Next Scheduled Network Starts.
Owner | Owner of the network to be activated Above this column, you can make an owner preselection. If this field only contains an asterisk (`*`), all owners will be displayed. Your selection is stored in the user profile and is available when you invoke this function the next time.
Network | Network to be activated Above this column, you can make a network preselection. If this field only contains an asterisk (`*`), all networks for the current owner selection will be displayed. The network preselection is possible only if an owner was selected uniquely. Your selection is stored in the user profile and is available when you invoke this function the next time.
Run | Run number for this activation.
Version | Version of the network
Job | If the activation is for one job only, the job name appears in this column.
Date | Date of activation You can enter a start date and/or time in the fields above the Date and Start columns to display only those activations due to start after that time. For valid date and time input formats, see Date and Time Formats.
Start | Starting time of activation.
Type | Displays the current status of the activation. Possible status types are, for example: `Schedule Table`, `on request`, `Schedule, active`, `Aw. Symbol Prompting`, `Symbol Entry in Progress`.

### Modifying Planned Network Start Times

You can modify a network start time only if a run number is assigned to the network planned to start (be activated).

To modify the start time of a planned network activation

1. On the Next scheduled Network Starts screen, enter `M` (Start Time) in the line command field of the appropriate network. Press ENTER.

   A Start Time Modification window opens:

       |  Start                                         |
       |    planned   ==> 01.03.19  00:00               |
       |    new       ==> 01.03.19  00:00               |
       |                                                |
       |  Keep predefined Job Time Frames ==> N         |
       |                                                |
       |  -PF1------PF3------PF5---------------         |
       |   Help     End      Save                       |
       +------------------------------------------------+

2. Enter a new date and start time.

   Notes:

   1. A start time up to the current time plus "activation before earliest start" may cause an immediate activation or an immediate start of any job in the network.
   2. If there are already active jobs for this run, their time frames will be adapted synchronously.

   If required, change the setting of the Keep predefined Job Time Frames option:

   `N` | All job time frames will be adapted (default value).
   `Y` | Jobs with master time frame definitions will not be adapted.

3. Choose PF5 (Save) to save the new start date/time.

   Or:
   Choose PF3 (End) to save the new start date/time and close the window.

   If saved successfully, the new start date/time is entered on the Next scheduled Network Starts screen and used for the next network start.

## Displaying the Network Execution History

The execution history is a record of past schedules. It shows the days on which the network was scheduled for execution. The data on a History screen cannot be modified.

There is history data on past network executions for the current and for the two preceding years (provided the network already existed at that time).

To display the execution history

1. Type `X` in the line command field of the selected network. Press ENTER.

   A History screen like the example below appears. The display is in calendar format starting with the current half year. The dates on which the network ran appear on the history:

        29.10.08               ***** Entire Operations *****                    15:26:21
