ERV As Item Expense Class for Expense PO

Hi All,

We have created an Expense PO and matched it to AP Invoice with different Exchange rate. While Invoice Validation an ERV line is generated at distributions with PO charge account.

When we do Create Accounting ITEM EXPENSE Account Class is trigerred instead of ERV Class and can not find which account line related to my rate variance. This is cause while reconciling the balances.

1. Now we want to know how to find correct ERV line in Accounting in SLA as well in GL?

2. On what basis we can customise ADR, as we haven't seen ERV Class for Expe PO.
