AP PO Accrual Write off - report to break down write off amount between IPV and Exchange Loss/Gain?

Hello,

We perform AP PO Accrual write off. Create accounting job successfully creates entries for foreign currency transactions to Debit  Accrual Account and Credit IPV (Invoice Price Variance)  and ERV (Exchange Rate Variance) accounts.

For example: Debit accrual act for 200 , credit IPV 190 and ERV 10

However Accrual Write off Report lists the whole 200 transaction under IPV

CST_WRITE_OFFS  table stores IDs for all 3  accounts used in the entry - accrual, offset (IPV), and ERV -but the Write off total is once again lump sum of 200

I am happy with created accounting but how do I get a detailed report to show IPV/ ERV broken down?
