Update Infotype 7409 for PERF

Hi All

I have added the enhancement TMC_Performance while configuring the appraisal template in phap_catalog in the status flow. As per the logic, at the completion stage , the HRP7409 will get updated for the PERF values. This works fine. My issue is , as of now ,the PERF field in table is getting updated with the FAPP column value from template which is the standard column. I want to populate the same with z column created . How can I proceed further , please suggest.

Thanks
