IDOCs to send Employee Data

Hi All,

In my current project, I have lots of interfaces to send employee data to third party. Now the interface team has decided to use IDOCs to transfer employee data. Employee data is of the order of 20,000 and many interface will be scheduled to run daily. So here are my questions:

1. Earlier decided approach was to use file interface. Is IDOC better in this case?

2. Over and above this, they want to generate 1 IDOC per employee data (if the interface has to run every business day, then ~5 Million IDOCs per year and this is just for one interface). Do you think this is the right approach?

Appreciate you responce.

Cheers,

Bhaskar
