Comments | An optional descriptive comment for this step. |
Scope | The name of a document (IData object) in the pipeline to which you want to restrict this step. If you want this step to have access to the entire pipeline, leave this property blank. |
Timeout | Optional. Specifies the maximum number of seconds that this step should run. If this time elapses before the step completes, Integration Server issues a FlowTimeoutException and execution continues with the next step in the service. If you want to use the value of a pipeline variable for this property, type the variable name between % symbols. For example, %expiration%. The variable you specify must be a String. If you do not need to specify a time-out period, leave Timeout blank. For more information about how Integration Server handles flow step timeouts, refer to the description of the watt.server.threadKill.timeout.enabled configuration parameter in webMethods Integration Server Administrator’s Guide. |
Label | An optional name for this specific step, or a null, unmatched, or empty string ($null, $default, blank). For more information about branching on null or empty values, see Branching on Null and Empty Values. If you use this step as a target for another BRANCH or an EXIT step, you must specify a value in the Label property. For more information about the EXIT step, see The EXIT Step. |
Switch | The name of the String or constrained Object variable whose value will be used to determine which child step to execute at run time. Do not specify a switch variable if you set the Evaluate labels property to True. |
Evaluate label | Whether or not you want to evaluate labels of child steps as conditional expressions. Select True to branch on expressions. Select False (the default) if you want to branch on the switch value. |

That exact string | A string |
The String representation of the object’s value Example for Boolean object true Example for Integer object 123 | A constrained object value |
Any string fitting the criteria specified by the regular expression Example /^REL/ | A regular expression |
An empty string | A blank field |
A null value | $null |
Any unmatched value (that is, execute the step if the value does not match any other label) | $default |
Important: | If you are branching on expressions, make sure the expressions you assign to the target steps are mutually exclusive. In addition, do not use null or empty values as labels when branching on expressions. The BRANCH step ignores target steps with a $null label or blank label. |
