  Check Document Currency: Ensure that the currency is specified in the document or transaction you are trying to process. This can usually be found in the header or item details of the document.
  Review Master Data: Verify that the relevant master data (such as vendor, customer, or material master) has the correct currency settings. If the master data is missing currency information, update it accordingly.
