How to batch send existing POs through a new PO Output Condition? (EDI)

[Former Member]

Relatively new to SAP space and so I humbly submit the question below. I have exhaustively searched the answer to this issue, and I believe my inexperience prevents me from even finding the right terms to build a query.

Our company has recently integrated with an existing supplier through EDI. The supplier has requested re-output of all existing PO's through EDI to sync their system.

We use tcode MN04 to establish the output condition, which works just fine for new POs. However, is anyone aware of a method to, in a batch, re-output the existing PO's through this new medium (EDI)?

Thank you so much!

conditions are determined if a PO is created or changed.

So you would need to change the PO. And the most simple change without changing a field is to add the message condition manually to the purchase order.

Alternative adding the message condition via a function module, see this older discussion https://archive.sap.com/discussions/thread/751428
