We have updated the revised salary with the start date of 01/01/2014 in the table V_T7INA7 and V_T7INA9
Created the new base slabs in table V_T7INA7 for basic and HRA and assign it table V_T7INA9 grouping.
After move the above config to production server, the employee master data for some old employees in infotpye 0008 PA30 updated automatically with the new base slabs.
I don't want to change the past values in the infotype record with the revised amount, If anybody guide me, is there any config is missing.
