Can you manually change the rate on a customer invoice (CUSTORDDEB or COADVDEB)? It does not look like it is possible. My question is why the “Currency rate” field is greyed out when the invoice is in Preliminary status? Is there a config somewhere that is blocking that field? Is that standard way in IFS 10?
It seems like you need to create a currency rate correction (does not work for COADVDEB) and it creates 2 additionnel invoices, one to reverse the original invoice and a second one to recorded a new invoice with the correct rate. Is there a easier way than that?
