Vendor Mass Update

Hello SRM Folks,

We want to do mass update for vendors (Updating proxy bidding flag in Manage Business Partner) since we have 3000 vendors. It will be highly complex to update it manually. Could any one of you have gone through such experience then please share with us.

Is it possible to use LSMW or eCatt to update proxy bidding flag on vendor master (Transaction BBPMAININT)

Please let me know.

Thanks,

Amit
