Hi Dr. Reinhard,
I am really glad and appreciate your prompt reply!
As far as your queries on Accounting currency setup, invoicing currency and the origin of the vouchers are concern, i have already looked into those as all are having same currency as "AUD" only.
One of the example i have shared belongs to "AUD" origin as it's coming from a PO and project transaction, vendor transactions all are in single currency only as we don't have any other currency setup in system.
Your expert advise and help will be much appreciated.
WR,
Dinesh Sharma
