Also found issue with Work Overview. After approval leave request work item doesn't disappear from Work Items and when I execute the same, it gives ABAP DUMP -
In the source code you have the termination point in line 23
of the (Include) program "CL_PT_REQ_WF_ATTRIBS==========CM001".
The termination is caused because exception "CX_SY_REF_IS_INITIAL" occurred in
procedure "BI_PERSISTENT~FIND_BY_LPOR" "(METHOD)", but it was neither handled
locally nor declared.
