How to perform checks on incoming messages in Biztalk orchestrations

I am receiving a message from CRM in my Biztalk orchestration and that message contains one field called "Status" in it. Now I want my Orchestration to complete rest of the operations only if the status field is populated otherwise it should end. I know that we can use decide shape for decision making, but how do I check if the status field is populated or not to make decision? I have added the images of schema and orchestration.

.

Searched on google and found nothing useful

We did a workaround. We introduced a new API which will return Yes or No depending on which the orchestration will process further.
