Relevant Source is not available under Payables SLA to derive constant value for Class IPV.

In case of AP Invoice Accounting for the class Invoice Price Variance following account (140101) is getting derived which I believe is coming from PO charge account We want to define a different account for IPV for Source Payables (Under cost mgmt. we have managed this with cost elements/cost component mappings but same cant be done here) Unfortunately IPV is not available to define under Manage Common Options for Payables and Procurement unlike exchange rate variance accounts.

When checked under Payables Mapping set there is no source available which relates to IPV when search with keywords related to Invoice Price variance (Please refer 2nd screenshot below)
