Doubt on Sync-asynch Bridge

[Former Member]

hi all,

I was trying to understand the sync-asynch bridge concept and from what all i have read i have come to know that there is a sync-asynch and also asynch-sync bridge.This is used in a scenario say file-rfc-file.But i have done the same scenario without the bridge.I am still not clear where this bridge will fit into.

Can anybody please explain me with suitable examples..

thanks,

Hi,

File-RFC-file is Async-sync communication. There is nothink like async-sync bridge in BPM. Because for this, 3 steps are needed

1. Receive - async

2. send - sync

3. send - async

But for Sync-async scenario, a Sync-async bridge should opened using receive step.

Example : Http request - File && File - Http response

Steps:

1. Receive - open sync-async bridge --> To receive Http request

2. Send - async --> To send message to File adapter.

3. Receive - async --> To receive message from File adapter

4. Send - close sync-async bridge --> To send Http response

Example : http://help.sap.com/saphelp_nw04/helpdata/en/83/d2a84028c9e469e10000000a1550b0/content.htm

Hope this clears your doubt.

Hi,

In file - rfc - file , no need of Sync-Async communication.

Actually a communication between Syncronous and Async.

here file is async, rfc is synch.

Please gothrough this link to understand about BPM

Hi,

The scenario wat u did is example of "async-sync" bridge in general terms, but you dont specify any bridge in BPM. Its normally called async-sync communication.

I didnt get wat u said about file-rfc-file without bridge? Are you talking about RFC lookup? If so, its completely a different method to achieve the same async-sync communication.

For Sync-async scenario we need to specify a bridge in BPM. If you need to start a BPM scenario with any synchronous adapter you need to go for sync-async bridge.
