Control-M scheduling for IDOC scenario

Hi All,

We are in PI 7.31 AEX(Java only) and have IDOC scenarios (batch message split scenario, inbound File into multiple IDOCs 15000+ nos using multimapping).

Now we are introducing Control-M for scheduling in legacy/PI/ECC. And Control-M needs a status file to be placed once the last IDOC reaches the ECC box from PI, so that it can trigger the inbound ECC batch job for IDOC posting.

Looked into below options, however doesn't look like the best approach,

1. add one more mapping to create file and put "Maintain order at runtime" in Interface determination level.

     This will create EOIO scenario for all the IDOCs (15000+) and an additional file message, This will degrade the performance, since we have almost all the inbound interface has this requirement.

2. http://scn.sap.com/community/pi-and-soa-middleware/blog/2012/08/20/integrating-file-scheduler-with-sap-pi

    - Since we have IDOC scenario with multimapping/creating multiple IDOC, this doesn't looks like the best solution.

Please let me know if we have any better ways to achieve the above scenario,

Thanks In Advance!!!

Cheers,
