Accounting Error on Sub-Inv Transfer Cost Distributions BUT NOT on Misc. Trxns Cost Distributions

During our most recent month end close, we found that the accounting for the Cost Distributions of Sub Inventory Transfer trxns for one of our Inventory Orgs had errored out because the Inventory Valuation account was pointing to another Inventory Org (The company segment of the acc code combination was incorrect) on the 'Manage Mapping Set' FSM setup under Cost Management because of which the Offset account was not derived. We had this corrected so now the accounting entries were derived correctly (Inventory Valuation account —> Offset Account)

BUT also we observed that before the above correction was made, the cost distributions for Misc. Trxns (Receipts & Issues) for that Inventory Org, were accounted successfully without any errors HOWEVER we did see that the accounting entries were derived incorrectly since the mapping set was incorrectly configured like I mentioned above. We saw that intracompany accounting entries were incorrectly derived on the cost distributions for those Misc Trxns possibly because the inventory valuation account mapping set was incorrectly pointing to a different Org.
