I encounter this error message "reconciliation difference must be zero" when trying to reverse a manual journal entry involving foreign exchange rate. This message appears when the rate from the creation date is different from the rate on the reversal date. They just upgraded from 2005A to 2007A. They did not encounter this message when they were in SAP 2005A. They only encountered it after the upgrade. What shall I do? I would really appreciate if you could help me.
