  The SAP error message M8684, which states "All previously entered withholding tax data will be lost," typically occurs when a user attempts to change certain fields in a document that has already been processed with withholding tax data. This message serves as a warning that if the changes are made, any existing withholding tax information associated with that document will be deleted.
