As a basic rule, the currency cannot be changed if there has alreadybeen a goods receipt against a document.
If the document contains external service and/or limit items, or if aninvoicing plan has been assigned to an item, the currency cannot bechanged following the receipt of an invoice either.
If external service items exist, the currency also cannot be changed ifservices that have actually been performed have already been recordedor if the item in question has been assigned to a preventivemaintenance (servicing) plan.
