Vendor Consolidation and Mergers/Acquisitions

unknown

I'm interested to know how others handle consolidations and mergers/acquisitions in AP. Is anyone using the merge function within Lawson? We've heard there are issues with this program. Also, if two vendors have the same TIN #, but different names on their invoices, are these set up as two vendors or one corporate vendor that somehow references the two differing vendor names? If under one vendor, how do your AP reps search for that main vendor if that name and the TIN # is not on the invoice?

Thanks in advance for the comments.
