Asy-Syn bridge

[Former Member]

I have a scenario like

The XML PO data from the HTTP client is posted asynchronously to XI (using quality of service “Exactly Once”). The control is taken over by BPM and posts the BAPI synchronously into the R/3 system and upon receiving the BAPI response containing the PO number, BPM will send a message asynchronously to the legacy system, as a flat file.

Is this Asyn-Synch, does Asyn-Synch really exists. I would appreciate if anybody can explain me.

Thanks

Hi Krishna,

Thanks for the reply and in the same scenario, if the http client sends synchronus request, then it will be a Asyn-Synch bridge ? In that case what r the additional steps i need to have in my bpm to send the response back to bpm ?

krishna what is the differ between webservice and http client?

Thanks for your reply sneha

Hi,

If your sender is Sync,in the above scenario, then you need to have steps like. I.e Open Sync bridge and close the bridge.

For more -you can refer BPM Pattern in the SAP BASIS software component in the Integration Repository.

discussion on http and Webservice-from different views

Http client directly sends data into XI pipeline.

But Webservice is the case, you need to have adapter to convert XI understandable message format.

Generally Webservice is mainly used in the internet applications. and also for remote client

But http client is used when you have integration in the same landscape. http client is used by external systems to connect to the Integration Engine using the native HTTP interface i.e message with no SOAP enevelop

Hi,

In this case it is not Async-Sync Bridge.

It is just a Sync scenario with BPM.

Check this blog for reference-

/people/arpit.seth/blog/2005/06/27/rfc-scenario-using-bpm--starter-kit

BPM steps:

1) Receive the http message

2) Send the message Synchrnously to BAPI

3) Get the response and send the respose to file system

Assuming Mapping of 1) recieved message to BAPI Req 2) BAPI Response to Response TargetStructure is done outside the BPM
