Hi,
1) For 1DSD (1 day salary deduction):
You have to identify the payment wage types which are to be ticked with cumulation classes 36 & 37. Function INDSD automatically creates the technical wage types /3OE & /3OF. You may have to configure the calculation indicator in T7INO1 table.
2) For GPF & Group savings:
Depends on which info-type are you going to use for above wage types. Are you going to use IT587 or any other info-type ?
regards,
Bala.
