Payroll solution for country grouping PK

Hi Experts,

There is a requirement of payroll solution for MOLGA =PK for Pakistan. While saving the custom schema for PK grouping it is not allowing. This requires to make changes in table T500L with Payroll Solution as "Customer" and I need to use the cluster RX for results.

1. What will be the procedure and probable effects of making such changes?

2. Can there be any other reasons for which the custom schema is not allowed to save for MOLGA= "PK".

Regards,

RK.
