Creating additional screen field in Vendor Master at Company Code Level

Hi All,

I have to add some custom fields in Vendor master at Company Code Level.I have alraedy implemented a BAPI suggested by the system to add additional fields.

A new Button is coming after implementing the BAPI , which gives me a space to add new custom fields , which i have appended at LFA1.

My problem is that , the new Button is visible at each screen, i.e Button is coming at Address tab, Control tab, all screen correspond to company code and all tab correspond to purchasing.

While i want that Button should only be visible at screens correspond to company code.

Please suggest how to acheive the same.

Regards,
