How would biztalk run a multiple file input (all the same format and definition) and run into a single file output complete with
a running total on a trailer record on the output file with the total amount of transactions of all the multiple files processed?

thanks.

Hi,

I don't think BizTalk can support this natively.

You may be able to get close to what you want by concatenating the files together before placing them in a channel (via a custom pre-processor or a script that creates the files), setting the document specification to allow multiple occurrences of the main document and then mapping it to the destination document and using the count or sum functoids to populate the trailer elements of the output file.
