Hi
When using superannuation as monthly contribution, /3S1 is being generated is being generated should be copied from /3S1 with Cumulation class '17' ticked and cumulation class '24' & '25' not ticked.
So, maintain wage type characteristics to be rounded off as per your requirement in T511 for your LIC wage type.
Check table V_T7INS5 and maintain wage type for frequency and monthly contribution.
Function HR_IN_CALC_SAN computes the superannuation contribution and calls the exit EXIT_SAPLHRPAYINS_001.
It all depends on the contribution frequency i.e. monthly annually.
Thanks,
MAdhav.
