Chris, The type of EDI interchange routing information you're discussing is typically - and should be a key function of - maintained within the trading partner management component of any comprehensive EDI management system. It shouldn't have to be maintained external to such a system.
I think we also need to take care that we stay focused on the issue - identification of trading partners for routing of EDI interchanges - and not just focus on payer identification. Payer identification and provider identification for the business transaction is accomplished within each specific transaction. It would be too easy in this discussion to get out of scope and then get off course. Rachel Foerster -----Original Message----- From: Christopher J.

If we can identify all the data elements that would be in such a master-table AND a messaging system, then each trading partner could maintain his/her local table of "routing information". Of course, one would need that very routing info in order to collect the information to put in his local routing table! We got a bunch of chickenless eggs (eggless chickens) here! Ron's right though... we should develop that list of data elements first, and then figure out how to keep the current version in every sender/receiver's system. -Chris At 03:46 PM 1/21/02 -0800, David A.

Nonetheless the problems are the same. Christopher J. Feahr, OD http://visiondatastandard.org [EMAIL PROTECTED] Cell/Pager: 707-529-2268
