PARTNER_UPDATE modify custom field

Hi all,

I need to do some modifications in partner data, the problem is that the badi PARTNER_UPDATE is only triggered if a standard field is changed. The same happens with others badis like BUPA_ADDR_UPDATE.

I've added a custom field and I want to modify it and other things when the user push "Save".

Do you know if is possible to trigger this badi manually?

Thanks in adavance.
