Aggregate Tables will currently show “Aggregate” in the DW_SourceCode field. In some cases users will want to pass on the DW_SourceCode present in the original table or perhaps specify one of their own.
As system fields cannot be modified by transformations, changing this currently requires using a post-step or doing the aggregation in a Custom View or other feature.
Features like Table Insert already allow you to choose how to fill DW_SourceCode, having a uniform approach across features would be more consistent.
