Pass Through Scenario with no Mapping in PI 7.1

Hi,

My pattern is IDOC to MQ(JMS Adapter) without any mapping as my partner supports the IDOC-XML format. I imported the IDOC for outbound into PI.

Can I do a pass through scenario without creating any message type/interface for inbound. May be by using basis object(creating sender namespace dependency under receiver software component)?

If yes, what to use as recevier service interface in Interface deternation?

If No, what are my options? (should I need to create a data type/message type/service interface for receiver...? though it is a pass through..?)

Guess it is clear..if not pl let me know...will try to explain in detail...

Thanks,
