CO Validation for KP46 (Change Stat. Key Figure Plan Data)

Hi All -

As per business requirement, i have to create new validation for cost center while do SKF plan posting. I have tried creating validation in call point '001' and '002' in OKC7 transaction code, but it is not working.

I have created similar validation for KB31 transaction code it is working and i have done same steps for 'KP46' transaction code. Can anyone please suggest me how to proceed further.

Thanks in advance!

Rds,

Kannan
