Seniority based Contribution

Hi All,

We have a Savings Plan which is used by all category of employees.

But the contribution % depends on different date types. As per configuration we can override Hire date with some other date type.

But we need more than one date types for determining Seniority criteria. How can it be done???

Whether we will have to use BADI/Exits ??

Thanks & Regards
