Check Box in SAP Business Partner

Hello Everybody,

I'm working with BUPT and trying to place a check box in SAP Business Partner (Role: MKK).

Actually the Check box is delivered from SAP standard (Function Group: FSBP_05 and screen 0201) and I'm trying to custom it under Partnerdaten "BUP310". I have gone through the standard customizing procedure. Still the Check box field is not visible on the screen.

Can anybody please provide me a tip or any kind of Doku.

Thanks and Regards

Ravi
