Working with outbound iDocs

Hi,

I want to send data from R/3 to a legacy system. I want to use an iDoc to send the data. The legacy system expect to get a flat file that contains all the objects that were changed on a given day.

I find it much more easier to create the flat file containing several iDocs on the R/3 side (using the file port & packet definition) than using the XI for that purpose (BPM to collect messages and file conversion).

Am I missing something ?

Thanks, Nir.
