Paymode-X

I'm looking for Lawson customers that are using Paymode-X (Bottomline Technologies) to make electronic payments. The issues that we are facing are:

• Paymode-X assigns each vendor a 20+ digit identifier that needs to be entered somewhere in AP10 (APVENMAST). There are a couple of non-critical fields that can house a number of that size. Email, which we currently use. URL, which we currently use.
• Are have 8 GL and 8 AP companies and 2 Vendor Groups. We are not planning on having all companies use Paymode-X. Since multiple companies share vendors in the same Vendor Group, I would think that changing the Payment Code would cause problems between the Paymode and non Paymode companies.
