Hi All,

This document is to discuss OBJECTS_OBJREF_NOT_ASSIGNED dump we have encountered on our GRC system(GRC 10).

We had a scenario where certain users are unable to display/process their GRC request from the browser with HTTP 500 – Internal Server error ( Screen-1) on the browser and OBJECTS_OBJREF_NOT_ASSIGNED  dump in the GRC system(ABAP Stack).

Our security team investigated this for missing authorizations and they also deleted and recreated the user, but users still have this issue.

Screen 2 : ABAP dump on GRC system

Dump : OBJECTS_OBJREF_NOT_ASSIGNED

Runtime Errors OBJECTS_OBJREF_NOT_ASSIGNED

Excetion : CX_SY_REF_IS_INITIAL

ABAP Program CL_POWL_UI_HELPER=============CP

Application Component CA-GTF-SGF-POW



Reason for dump:

     On further investigation of this issue we understood that this issue was caused due the old query/queries cached for that particular user id and got corrupted. Hence when user tries to open his/her GRC session, system was executing these corrupted query and hence dumps in the system. As these quires are stored at database level against the user name, the attempt to delete and recreate the user id will not work in this case.


Resolution :

     We have run a report POWL_D01 to fix this issue. This report is used to clear the cache for the users to delete the all old queries .

This report allow you to input affected user id( multiple selection available) and you can run in display mode to view the current queries.

Check box ‘DISPLAY’ will allow you to view the queries before deleting them, remember to un-tick this box to cleat the user cache


Screen 4 : Report output on deleting the user cache

Result :

     User will be able to run new queries from browser without any dumps.
