Why is error 3887 generated when attempting to pay a foreign invoice in domestic mode?

Error 3887 indicates that the Currency Code in Customer Ledger Inquiry (P032002) is displayed in a different mode than the Currency Code in Receipts Entry (P03103). If you want to pay a foreign invoice in domestic mode, you will have to populate the Currency Code field with an * in Receipts Entry prior to pressing F16 to access Customer Ledger Inquiry. Then the Currency Code field in the Ledger will display an * and you will be able to select that invoice with a 4 and return it to Receipts Entry with the domestic amount displayed.
