Can someone please help me on the below scenario?
Backorder processing works fine for order not having plant substituted items, however for items/sub items with substitution, rejection reason is applied and items become unconfirmed.
1. How is the rejection reason set for the line items 20,30,40?
2. Is there any setting in Backorder processing for not touching the confirmed line items in case of RBA (plant substituted confirmed line items)
