Dear Rajesh,
Not all objects in table SRRELROLES can be reorganized by report RSRLDREL.
Data from table SRRELROLES with OBJTYPE BUS* are usually object links for business objects. You can look up the business objects in Tcode SWO1. For Example BUS2000126 is for Activities.
Usually user can choose to archive these data for better performance.
We do not recommend to delete these entries from the table directly. You should set up arhiving/deletion strategy for main business transactions. You can only delete those entries from the table when related activities are not needed anymore.
Best Regards,
Ellen
