Interface not found in Recevier Determination

Hi,

I am trying find out why I cannot see the interface i created in the IR in ID. The sceanio is IDOC via HTTP to XI to R/3.

2 Comm channels are setup, 1) HTTP sender for business service and 2) an IDoc recvier for the R3 system.

The repository project only conatins a Message Interface (abstract, asyc) created from an imported IDoc structure.

When I go to create a new receiver or interface determination, I cannot see the interface....am i missing something?
