Different tag for first and subsequent payments in DMEE

[former_member586104]

Hi

I am working on an MT103 payment file for vendor payments.

It all works ok, but our bank has now informed us that while the header for the first payment document should start with the usual ":20:" tag, subsequent payments within the same file have to start with "-:20:" Why they can't stick to standard MT103 format is beyond me but I don't think they are likely to change their "standard" just for me 😞

Can anyone advise how I might achieve this in DME? I can't see a condition that would be triggered on first but not subsequent payment documents (or vice versa).

Thanks
