Accounting document value different from billing document
I created a accounting document from billing and surprisingly the amount in accounting document is different from the billing.
We have a condition type where we want to apply XXXX exchange rate instead of standard SAP Exchange rate. We coded this in billing document user exit and it worked fine in billing. Now, when we release this document to accounting, system doesn't populate the billing document value. It populates the value which would have been obtained if we had used standard Exchange rate.
Can some one suggest where can I look up or any user exits in accounting document where I can write a code to pull the value from billing.
