Data integrity between SD/OD orders

Hi everyone,

We are currently running JDE EnterpriseOne version E9.0 on an AS400.  Six months ago we implemented the SD/OD process to handle our direct shipments from our vendors to our customers.  Over the course of time, we have determined that some of the changes to the OD orders occasionally get out of sync with the SD orders particularly when the users are adding new lines to the orders.  After reviewing the JDE documentation, I have 3 questions:

1. I have been instructing our users to be sure to add the new lines in the SD order entry.  They are assuring me that they are doing that and yet I still have OD lines that do not have any SD related order information.  And when I look at the the purchasing ledger file F43199, the program id on the new line is "EP4310" and not "EP42101".  Does the "EP4310" mean that the users really are adding the line in the P4310 program or could they be using the P42101 program and an embedded business function is calling P4310
