Creating Custom mapping set for natural account in receipt accounting

Summary:

We've a custom mapping set for Trade in-transit valuation but due to some reason it has stopped working & default account is hitting.
This is only for TO & PO receipts where every transaction goes to different GL account based on the item categories defined.
This was working fine until Jan-24 but after that all these transactions are going to the standard/default account and not the custom one.
