Retrieve a field from Data Bidder

Hi Gurus,

I've a problem to retrieve field "Allow Bid by Proxy" that comes from transaction BBPMAININT. This field is a flag from table BID000-BID_ON_BEHALF in General Data Bidder and it's menu is part of Data Vendor.

Data element is BBP_BID_ON_BEH but don't exist any table in SRM system that contains some data for this field. I'm looking for more functions module that returns data vendor or data bidder but they don't work because SRM tables are not filled.

I need read this field from a external report to execute Batch Input, but I don't know what else to do.

Any idea??

Thank you very much for all. Regards.
