Mass PO update - adding new line items
We are closing down one of our plants. So, business wants to move all the existing open POs (based on quantity only, not invoice) against this plant to different plant. Decision was taken not to create new POs with different plant against these open POs. Here what is required - mark all the open PO line items for plant A as delivery completed, and in the same PO, add new line items with the same material and open quantity, but with plant B.
I can get the list of all open PO line items with all details, and even mark them for delivery completed.
My main concern is - what would be the best approach (w/o technical help) to add multiple line items in existing POs? Can I use LSMW?
