Change aggregation behavior

By default, when permanently aggregating process instances using the PPM command line aggregation (see runppmcompress) (see PPM Operation Guide), identical values of a process dimension are transferred as a dimension value to the aggregated EPC, while different values are deleted so that the dimension does not have a value in the aggregated EPC. You can then no longer trace whether dimension values had been specified or not. This only applies to dimensions that do not function as aggregation criteria, i.e., dimensions that are not included as iterations in the aggregation paramset.  

You can change the behavior of the command line aggregation through specific configuration settings in your PPM system so that both identical and different dimension values are deleted during aggregation if this dimension is not used for iteration in the aggregation paramset. In the aggregated process instance, the deleted values are then rendered visible by a uniform aggregation value. You specify aggregation values in the measure configuration for the relevant process dimension (text dimensions and search dimensions).

For time dimensions (timedim and hourdim), you can only specify that both identical and different dimension values are to be deleted during aggregation. In the analysis, the dimension can no longer be represented in the aggregated process instance due to the deleted values.

Text dimension example (aggregation value for the Material process dimension)

s_ppm_tr_customizing_57

All values of the Material process dimension in the selected 46 process instances were deleted via command line during permanent aggregation and replaced by the aggregation value specified in the measure configuration (Compressed (1st level ID)). It does not matter whether the dimension values were identical or different.
