Dimensions are defined together with measures in the client-specific measure configuration. The PPM system makes a distinction between the following dimension types:
Dimension |
XML element |
Description |
---|---|---|
One-level |
oneleveldim |
One-level dimensions are used if the number of dimension values is low and no meaningful grouping of the values is possible. Example: Name of the source system, input channel for a call center (e.g., call, fax, e-mail) Attribute data type: All. Numerical attribute values are converted to text. |
Two-level |
twoleveldim |
Two-level dimensions are used if meaningful grouping of the dimension values is possible. Example: Process type group/Process type, Material type/Material Attribute data type: All. Numerical attribute values are converted to text. Dimension values are saved as the TEXTPAIR data type. |
N-level |
nleveldim |
For text dimensions with more than two levels. |
Floating |
floatingdim |
Dimension is based on floating point values. The dimension values represent particular intervals. Example: Order volume Attribute data type: DOUBLE, TIMESPAN, PERCENTAGE and all user-defined types derived from them |
Time |
timedim |
Indicates the change of a measure over time. Attribute data types: |
Time of day |
hourdim |
Indicates the change of a measure over time. Attribute data type: TIMEOFDAY |
Period |
timerange |
Indicates the change of a measure within a specific period. |
Search dimension |
searchdim |
Search for process instances using attribute values Attribute data type: TEXT Search dimensions cannot be displayed as dimensions in the analysis. |
The attributes required for creating text and floating point number dimensions are specified in a corresponding dimitem XML element. If the referenced attribute is an attribute to be calculated, this must be specified (calculated="TRUE"), so that the attribute can be calculated before creation of the dimension. In addition, you need to specify whether it is a process or function dimension.
When defining dimensions, ensure that the data type of the referenced attributes is compatible with the selected dimension type.
