SHDB for FK02

Hello All!

I need to change massive data for all vendors in our database, W/tax code if Wth.t.type = I1 for example. However, this value could be in different lines in the With/tax information grid wich is hard to discover where this code is.

When I record a SHDB, it is recorded the parameters based on the test I made.

Question: Does exist a BAPI or other way to update those information more efficiently? I tried BAPI_VENDOR_EDIT but it opens XK02 and it's not convenient.

Thanks,

Michel
