Routing messages in BPM

[Former Member]

Hi,

I have the following scenario:

I send an IDOC from SAP R/3 to PI. In PI this IDOC is sent to a BPM.

In the BPM an select-statement is performed to get additional data from an external database

Then a mapping is performed and I have to update the same database with the new data.

Now it is getting more complicated because I have 2 sending R/3 systems and 2 receiving external databases, but I have only 1 PI system

So,

System A ---> PI system Z --> select-statement in database X --> PI system Z --> mapping --> update database X

System B ---> PI system Z --> select-statement in database Y --> PI system Z --> mapping --> update database Y

It is possible to route the select-statement to the correct database using Context-objects in the receiver determination, because SNDPOR is still filled with the R/3 Port. After the database select this context is not available anymore. So I can not route the update statement anymore.

How can I fill context objects with the correct data?

Thanks

What do you mean by ""this context is not available anymore"?

What are the steps you are using in your BPM design. Can you describe it a bit more.

Hi Jaishankar,

The BPM looks like this

Receive step --> receiving the IDOC in the BPM

Synchronous Send Step --> select statement to database

Transformation Step --> to determine the database updates

Synchronous Send Step --> update statement to database

In the receiver determination (configuration) of the first synchronous send step I can use the Context Object SNDPOR, because this contains the port of the sending system (eg SAPA or SAPB). With this information I can find the correct receiver (eg when SNDPOR = SAPA go to database X)

But in when I arrive at the second send step SNDPOR is nog filled anymore. So I don't have the possibility to find the correct database.

Is there a way to store this info somewhere in context objects?

Ron,

Do this particular check inside your BPM. Use a Switch step and evaluate the content of SNDPOR.

The modified BPM design will be some thing like this...

Receive step --> receiving the IDOC in the BPM

Synchronous Send Step --> select statement to database

Transformation Step --> to determine the database updates

Switch -->evaluate the content of SNDPOR

Branch1 -->Synchronous Send Step --> update statement to database (To db1)

Branch2 -->Synchronous Send Step --> update statement to database (To db2)

P.S: I was held up in a meeting and hence the delay

Hi

Thanks for the tip! I'm goig to try this one.

I would have had it a little bit more flexible, for possible future extensions. But for now this will do!
