Synchronous RFC functions from XI

[Former Member]

Please confirm my observations.

I wanted to call a synchronously RFC Function i.e. Importing some data and Exporting some reply.

The XI message monitor shows that the RFC adapter handles this call asynchronously i.e. QOS of EO and not BE as I would have expected.

Is this behaviour I observe correct and does this then imply that there is no way of calling RFC enabled Functions on SAP expecting anything back

Thanks

Hi Andre,

if you send from R/3 just find the right ABAP to determine synchronous/asynchronous:

CALL FUNCTION myFunction

DESTINATION myDest

IN BACKGROUND TASK "only for asychnronous messages

...

COMMIT WORK. "only for asychnronous messages

If R/3 is the receiver, then the sending system determines the quality of service. For example a http message should have an additional parameter QOS=BE/EO/EOIO.

Hi,

You can do it in both the ways i.e. Synchronous as well as Asynchronous. Check your Message Interface. Here you have to check the attribute as Synchronous.

Hi Vishal,

The RFC Adapter has no place to specify the QOS. The interfaces are marked as synchronous.

Could you maybe supply an example of such an scenario ?

Thanks

Hi,

Have a look on this weblog /people/arpit.seth/blog/2005/06/27/rfc-scenario-using-bpm--starter-kit

Hi Andre,

I have told nothing about RFC Adapter. I think your scenario is file to RFC. I hope u r calling a RFC from a file i.e XML input from file is given to RFC. That is obviously Asynch and QOS will be EO as specified in ur communication channel. check the correct one.

Thanks and Regards

Hi Andre,

What is your exact scenario?

From where you are passing the input to the RFC.From a XML file.May be you are checking that QOS.

Hi Sudharshan,

I'm doing SOAP <-> XI <-> RFC or attempting in any case. Just wiped my whole config. Going to start over and do it with the BPE.

Thanks for the help

Hi Andre,

The RFC calls are for synchronous data processing by default.

You can send and receive data from a RFC enabled FM.

you can make it asynchronous using BPM though

Hi Vijaya,

Here is the message seq from the monitor for a call to a synchronous Function module :

The Audit log also shows that the call was handled asynchronously -

Any iead what I'm missing ?

H Andre,

Please can you check if the message interface is syncrhonous and also that you have given the message type correctly in you MI.

You will have two Synchronous MI with reguest and Response Message type. Also, two message mapping, one mapped request to request and other response to response.

regards

Vijaya
