JPMorgan payment connection

Hello,

I would like to understand the payment file specification details from SAP ECC6 to JPMorgan.

JPMorgan currently supports SAP IDOC files and XML data files. Through JPMorgan's translation facilities, clients can produce standard output files from their internal systems, and JPMorgan then translates the files into the required processing format. No longer need to understand the intricacies of  JPMorgan's proprietary file (such as GFF) specifications and requirements.

Can anyone know what specification of the standard output file that generates from SAP?

Thanks.
