Hi everyone once again I have query as to whether anyone has done the following before: On Project OnAccount lines to have a field to specify the excahnge rate to use when posting invoice for that line. The reason is because we want to invoice a deposit invoice at a certain rate and then later at the final billing reverse this invoice. The problem is if it is foreign currency and in different months then the base amount reversed will not match the original. We do not want to set a fixed rate for all the onaccount lines just certain ones and when we do invocing we will only be invoicing one line at a time so there is no issue of mixed exchange rates on the same invoice I am guessing this might be easily done but not familiar with the project invoice posting so not sure where to start Thanks for any help or hints where to start looking James
