Kindly check the following :-
A)SAP note 2168787 is implemented completely and consistently in your system, both manual steps and code corrections.
B)Wage Types /143 and /144 are calculated/appearing in RT of the employee payroll. For this to happen , as explained above, you should have the cummulation class 43, 44 ticked for the such wage types relevant for NPS basis.
C) Execute the payroll and check INS80 output IT table .
Thanks and Kind Regards
