File based Sync-Async Bridge

[senthilnathan_natarajan2]

Hi All,

I have a scenario where a file is available in a shared folder.

This file needs to be picked by a RFC Function module called in a Synchronous mode and the contents of the file needs to be displayed as the output of this RFC.

Is this achievable using Sync-Async Bridge.If so can someone explain me the steps to achieve the same?

Prabhu..this weblog refers to a Async-Sync Bridge.I am looking for a Synch-Async bridge

Prateek,The second blog,

solves my problem.

Thx a lot.

Senthil,

If i'm not wrong, the Synch-Asynch bridge refers to Synchronous Sender and Asynchronous receiver. But in your case its other way around.

OK , now tell me wht u want to do with the RFC response, do u again need to write it to the file?

Best regards,

raj.

Actually my sender is a RFC function module in a synch mode.The response of this RFC should be the content of the file which needs to be picked in a asynch manner(I think File adapters work in asynch mode only).Is this not a sync-async bridge? Pls correct me if i am wrong.

I'm sorry Senthil, I thought its File -RFC scenario.

Best regards,

If i were to open a Sync-Async bridge, I need to do the following

Step 1: Receive step to open the sync/async bridge

Step 2:Asynchronous send step

Step 3:Receive step

Step 4: Send step to close the sync/async bridge

In my scenario.

Step 1: Receive the RFC's request message

Step 2: ????

Step 3: Get the message from the file

Step 4: Transform the file's message to RFC's response message

Step 5: Send the RFC's response message

Moreover file adapter works in a polling mechanism..
