ABAP Proxy communication mode

Hello Experts,

I have a query regarding the ABAP proxy communication with an SAP system.

The scenario is as follows.

File -> SAP PI -> SAP ECC.

There are some data level issues (as per the proxy logic) with few messages being sent to the ECC system and hence they fail in ECC causing a block in the qRFC queues.

Now the problem is, this block is causing some valid messages from being processed which are stuck down in the queue.

Is there a way to change the qRFC mode of transport to tRFC so that each message can be executed independent to one another in the proxy ?

Any help in this regard would be helpful.

Thanks,

Ravi.
