IDOC to JDBC synchronous scenario

Hi All,

We have the following requirement:

Idoc will be sent from ECC to SAP PI and from PI we update MS SQL server using JDBC receiver adapter synchronously and get the insert/update count as response and send this response back to ECC as ALEAUD or SYSTSTATUS idoc along with the initial IDOC number. So that status of the original idoc gets updated at ECC side.

We have SAP PI 7.31 single stack system.

Following are my queries:

- Can this be achieved using BPM?

- with BPM, how can we send the original IDOC number in the status IDOC  which we send back to ECC, is it through correlation feature  ?

- Can this be achieved without BPM?

-- How can we send the original IDOC number in the status idoc which we send back to ECC, without using BPM?

Kindly help with suggestions.

Thanks,

Jane
