For one-, two-, and n-level text dimensions, you can import dimension values (especially comprehensive level descriptions) into the PPM system before the actual PPM import. Dimension values consist of a mandatory ID and an optional description.
Advantages:
You can create planned value definitions in PPM before process instances are imported.
You can significantly reduce the data volume of the process instances to be imported during the actual PPM import by not specifying the level descriptions already imported.
