We have a need to start archiving some Production Orders in our R/3 to help with performance issues. Some of these Prod Ord have external ops, therefore, have a PO that reference that operation. R/3 does not allow you to mark that Prod Ord for deletion unless the reference PO line is deleted. I tried marking the PO lines as 'blocked', but that didn't work so you MUST mark it as deleted.
The prod order have been TECO'd, so when you go into the PO's and mark it for deletion and save it, then SAP will not let you un-delete the line since the object it references is TECO'd.
What I'm really worried about is the impact of marking all these completed PO's (GR & Inv completed) as 'deleted'.
Any help would be great.
