Authorization to restrict on Partner functions

Hello Everyone,

We have a requirement to restrict Partner function on specific customer number as shown in the XD02 screen shot.

Eg : it should throw me an error when I tried to maintain sold to party partner function for the certain customer number..

The object F_KNA1_AEN with activity 06 controls overall restriction , but not for specific partner function and customer number.

Please advise whether it is possible to do this using standard SAP controls.

Thanks,

Sanjeev.S
