PO Charge Account is not being generated for Inventory Items.

Summary: PO Charge Account is not being generated for Inventory Items.

Checked the following Mapping Sets:

Expense Accrual Account - Business Unit

Invoice Price Variance

I also created a custom segment-level Account Rule and added two mapping sets: one for Expense Account and another for Inventory Item.
The same configuration is working correctly in the Test environment. It appears that some setup or mapping is missing in Production.

Errors encountered:
The account for account type PO Charge Account could not be determined because there are no mappings for the mapping set Purchasing Expense Account - Item. (PO- 2055554)
