Hi,
If you are trying to change the currency for a PO for which GR or IR is done, then the system will issue the message 06489 (Currency can no longer be changed) and system wont allow to change the currency. Double click on the message where the system will show the details.
In short, you cant change the currency in a PO for which the GR is already posted. Reverse all subsequent docs (GR and IR for the PO) and then change the currency. System will allow to change the currency in this case.
Regards,
