Stop Inbound IDOC's from being created

I want to stop inbound IDOC's for a particular partner (type LS) from being created in our R/3 system. Is there a way to do this? I am aware these can be stopped in the middleware, but this is not possible in our case.  I am also aware that I can stop these IDOC's from being processed via the partner profile, however, there will be a huge number of useless IDOC's that will be created in our system and I want to avoid that.

Hence, I do not want the inbound IDOC's to be created in the first place even though they are transmitted to SAP. Is this possible?

Any inputs will be highly appreciated.

Thanks,

Raghu.
