In the Inventory postings form, currently in D365, we can map Main accounts in the combination of Item / Item groups and Vendor/ Vendor groups/ Customer / Customer groups.

For the purchase related main accounts, the setup is given under Purchase order tab in Inventory posting form. The same setup works for both Purchase order and Purchase returned order.

However, we have received a critical client requirement where Main account mapping for Purchase returned orders is separately required, so that Purchase and Purchase return balances does not get combined in one main account.

I would like to consider this requirement to enhance the posting setup form for return type scenarios in Purchase.
