User master update schemes

User master update schemes enable the mass maintenance of user master data. A scheme defines the content of a user master data field and covers exactly one data source type and one user master data field.

Scheme rows can be created to define field names, regular expressions, and replacement terms. The replacement terms define in which form the source field content is transferred to the target field. Results of scheme rows are combined, and the end result transferred into the target field.

Class implementations can be used instead of defining scheme rows. An ABAP class implements the interface /DYNAM/IF_UM_UPDATE_RULE_IMPL and provides more possibilities than scheme rows in terms of changing data that is not directly contained in user master records.
