I have an EDI Customer that is problematic. The customer has multiple DCs. They transmit all orders under the same EDI ISA/GS Sender IDs using an N1*BS segment. They use centralized billing and would like for us to send 810 invoices back using thier same ID. The problem is that they use two differnt sets of SKU Numbers for our items (for macola item number QQQQ, some DCs use ABC123, and some DCs use 789XYZ). Any ideas on how I am supposed to do this? We are currently using Gentran:Server. If I use a parent/child relationship how will the inbound file know which customer? If I do a single company, how do I put in the two seperate sets of SKUs and have them attach to the correct Alt Address in the invoicing? Help?!?
