We have identified an inconsistency between Ledger and Project posting for certain type of adjustments. Specifically, we find different results on the ledger and project side if adjustments are performed after the exchange rate relevant for the initial posting has changed.

This issue is happening in item and expense transaction. However, in expense transaction, when adjustments are made after exchange rate is changed, it only affects the posted project transaction and not the voucher transaction. In case of item transaction, it does not affect the posted project transaction, but the voucher transaction amount gets changed.

Exchange rate change can happen because of one of the reasons:

• An actual change of the default rate (because of issues or agreements).
• Because the initial posting was made with a manually set rate (it is possible to override the system rate).
• Because of the 24 hours gap between the import of daily rates.

Customer Impact: This leads to an inconsistency in posted voucher transactions and affects their financials. There is no workaround for this as of now.
