An invoice Idoc coming from an interface into SAP issued the above error in t-code WE02 status 51. I simulated a similar posting in FB01 but got a different error 'Document contains VAT reg no but no EC relevant tax code' so i maintained a value in Field EU Code/Code, simulated the posting again and that error F547 resolved. When i reprocessed the Idoc in WE19, Message no EA709 was issued 'Idoc no was passed to application. I checked new Idoc number in WE02 and error was same as previous Idoc.
Please help and if you need more information let me know.
