I have a requirement to populate a WT which should be derived from a WT already existing in the system say for eg - WT 7777 (in Infotype 0015) is already in the system and a new WT 8888 to be created which will be 12.8% of WT7777. I tried writing a PCR using the constant for value 12.8 from T511K table. also, included the PCR in the payroll schema. But i am not getting the desired result. Can someone guide me on the same.
