Move local file to 2nd server and then place RFC call

Hi All,

Ihave a typical scenario. It goes like this:

The user has an encrypted file on his local computer and is connected to Server A.

This file needs to be decrypted using a utility set up on a server (Server B) other than the one he is logged onto (Server A).

So, the file needs to be downloaded into a common working folder on Server B.

An RFC call is to be placed to execute the decryption utility on Server B.

The output of the program is to be redirected to a text file to check for error messages.

Once the file has been successfully decrypted, its contents need to be uploaded into an internal table for further processing in the transaction running on Server A.

My questions are as follows:

a) Is this scenario possible? Can a user place an RFC call to a program residing on another server without being logged onto it?

b) Is this process possible simply by using a Function Module? If yes, which one?

c) Can ALE help me in this scenario in any manner?

Your help is higly appreciated.

Regards,

Madhur
