getting the error when i am trying to change the Assignment Category field of employee

I am facing similar issue as describe in below bug, I am trying to change the assignment category from assignment screen for an employee and getting error as-

FRM-40735 POST- UPDATE trigger raised unhandled exception ORA- 01403

document: from the note I found Doc ID 1626879.1

and checked the data in from the query mentioned in document-

For each impacted assignment run below query

select * from pay_object_groups where (SOURCE_ID in (select person_id from

per_all_assignments_f where assignment_id = &ass_id1) and SOURCE_TYPE = 'PPF')

or

(SOURCE_ID = &ass_id1 and SOURCE_TYPE = 'PPF')

this query returns nothing for me, can you please help in getting the issue resolved.
