Prerequisites for Class Templates
Before performing the first import of classes from an external source, run the Datamapping Sync Application Engine process (HRS_DM_SYNC) to synchronize the data mapping tables.
If you have updated the data mapping, run the process again to make sure that the tables are synchronized before importing classes. You should run the data mapping process periodically depending on how often you add records to any of the categories that are used for data mapping.
