title: Is there a requirement in BizTalk that requires a message coming in be sent out?
body: <p>I have an orchestration that processes incoming messages that make a data call. If data is returned, a new message is created and sent back to the receive port via a &quot;mover&quot; BizTalk application. The original message is no longer needed, so I've been sending it to a discard folder. Is there a requirement in BizTalk that requires a message coming in to be sent out?</p>
