Erase field in BDOC BUPA_MAIN

Hi Experts,

I have a CRM 4.0 system which is connected to R/3 system. For the communication between these two systems I use R/3 adapter and <u>NOT</u> XIF adapter.

After the maintenance of a business partner I would like to erase a standard field. The best solution would be to delete this field form the BDOC, but the standard BUPA_MAIN BDOC is built on standard structures and I do not want to change those.

I do not want to transfer one of BP standard fields to R/3 because we maintain this field on R/3 side based on strong business requirement.

Thanks for the help in advance.

Regards,

Tom
