I am executing transaction F110 and generating a DME file using SAP standard GB_BACS format. I have configured the bank user number on T042M as directed by SAP i.e. '....123456'. When the file is produced for transmission to the bank (Bank of Ireland) the user number displays as '....123456'. This is rejected by the bank as the format should be ' 123456'. If I change the the entry on T042M to read ' 123456' then the leading spaces are ignored on the DME and the user number displays as '123456'. Again this is rejected by the bank. Has anyone had this issue and if so do you have a way around it?
