EDI Related Customer Master Questions

I have a few EDI related Customer Master questions.

There is a need to establish a flag to accurately identify bonafide EDI Customers.  Because we send faxed customer PO's to a Fax-to-EDI service which converts them to EDI documents, and we rout warehouse orders for all customers via EDI to 3rd Party Distribution Centers, we enabled all customers for EDI processing in Customer Billing Instructions.

There is a need to ensure all new bill-to addresses are enabled for EDI processes. 

There is a need to ensure all new ship-to addresses for ASN Customers are configured with the appropriate ASN configuration.
