Replacing a legacy interface

Hi Guys,

Anyone have any thoughts on the best way to replace a legacy outbound interface from SAP. Current scenario is :

ABAP program extracting data (lets say its customer master data), writing to a file which is then FTP'd.

Implementing this via XI I believe options are :

Option 1. Don't use XI. Continue with current process. Benefits of this - cost. Drawbacks - Political, as this would go against the new integration strategy which is to use an integration hub solution.

Option 2. Use exactly the same process to produce the file. FTP the file to XI and get XI to despatch it.

Benefits - Limited cost implications, Satisfies political initiatives. Drawbacks - Are we complicating things just for the sake of using XI.

Option 3. Replace the writing of the file with a IDOC/BAPI/Proxy call to XI which is converted to file and dispatched. Benefits - utilising XI as it should be used. Drawbacks - Unnecessary cost and risk. Why replace a perfectly functioning process?

Any thoughts, greatfully received.

    In my opinion:

    Best ways is to create an ABAP proxy re-using your old ABAP source code, sending it to xi creating a file receiver.


    1. using your already made program.

    2.Moving into a central Interface monitoring solution with XI (HUB).

    3.Leverage the Software logistics of XI as the main object repository for your organization interfaces.

    4.>Why replace a perfectly functioning process?>

    fast adaptation to organization changes of Interfaces.

    Best Regards

      Hi Shravan,

      Thanks for your thoughts. I totally agree with your thinking, however as usual a logical decision can ofter be overpowered by political objectives.
