We recently migrated from AIX to Windows server. I have a flow that notifies the receiving clerk that an overshipment message (PO52) has been released. It queries the RM data to find the user's email address based on the user id that created the receiver. But now in Windows the user id is NTXXXX so the flow is failing to find this user in RM. Is there some place that ties the original user id with the NT user id and I can bring the original back into the flow?
