When you compile your BizTalk project, you receive the error:
“you must specify at least one already-initialized correlation set for a non-activation receive that is on a non-selfcorrelating port”.
This is a very basic mistake and usually, occurs due to developer forgetfulness.
This error can occur if your orchestration has no activating Receive shapes (Activate = true) or has no activating Receive shapes and is not called directly by another orchestration.
If your orchestration is not called by another orchestration, you must configure one of the Receive shapes to be an activated receive. For more information about configuring the Receive shape, including links to correlation, see How to Configure the Receive Shape.
