Bypass Scenario-- Need help.

Hi Experts,

New to XI..

Iam doing a bypass scenario..

I got the IDoc-XML from source and i need to route it to SAP system.

There is no need of doing any design part for this scenario?

No need of doing any mapping to acheive this??

No need to import idoc from SAP ?

Because frnds are claiming that we can acheive this by doing only configuration part.. Adapters will take care of picking and posting this idoc-xml..

can i achieve this w/o doing Design part ?? If yes pls provide the brief steps how i can achieve this..

Thanks in advance..

Regards

Reddy.
