This problem occured in multiple number of contract release POs. We use a customized header condition type ZHES as a PO clearing charge which is also a group condition.
At PO header level we maintain a current fixed exchange rate as well.
Problem is once it's maintained it doesn't give the correct local value or the USD converted rate. It gives an abnormal figure and even this figure shows value X at change mode and value Y at display mode.
I just can't understand the cause for this abnormal scenario
