Vendor custom field into master data tab (XK01 - XK02 - XK03)

Hi,

I need to add custom fields to my vendor master data.

i already added these fields using BADI (IF_EX_VENDOR_ADD_DATA and IF_EX_VENDOR_ADD_DATA_CS). So now I have a button on my XK03 tcode.

I would prefer to have theses fields with the master data (first screen) and of course i don't want to modify directly the standard screen. (no screen painter on standard program).

do you know if it is possible? And if it is possible how to do that?

Thank a million.

Mathieu
