We use SAP and are forced to create duplicate vendors if the vendor has more than one remit-to address. Do you know of any way to avoid this duplication? Our IT department says there is no fix for ...

We are not sufficiently familiar with SAP, though on its face, this would be a very bad practice. It seems unlikely that there is not a solution to this issue in SAP other than creating a duplicate vendor entry.  At the very least, perhaps there is a way for two vendor entries to be connected by number—perhaps a root number with variable extension, for example?

You question is a good one to post in The AP Network’s Forum, where other members who may have faced this issue could reply with a solution. If you are part of the SAP user group, that would be another possible source of a solution.
