cmp_Salary not updating with grade_id thru Assignment Mass update HDL

Hello,

We restructured our grade system. So we have totally new grades loaded thru HDL and old grades inactivated thru HDL.

Post which, we performed mass assignment update thru HDL.

New grade is reflecting in both Assignment screen and Change Salary screen.

Whereas when it comes to backend tables, new grade id is reflecting only in per_all_assignments_m and not in cmp_salary .

We dont have grade step progression or grade ladders or positions.
