Aggregation rules
An aggregation rule can be created, and an existing aggregation rule can be edited in preparation for an aggregation scheme.
Aggregation rules summarize users from one or multiple data sources to assure they are only considered once in terms of licensing.
By selecting one of the options for field transformation, it is possible to transform the contents of a user data field. A regular expression can be entered and, in case of success, replace the result by using a replacement string. All patterns available in ABAP for the REPLACE statement can be used here. Alternatively, an ABAP class can be used to execute transformations. The ABAP class has to implement the interface /DYNAM/IF_AGGR_RULE_TRAFO.
Templates for aggregation rules exist and show how aggregation rules can look like.
