change set doesn't appear in outgoing

I can't printscreen because the policy of compnay forbid it.

I am using  in Visual studio 2010 editor .

And after I do the following step

• Right click on the stream1 and open it.
• Scroll down till you see Flow Target option.
• Add stream2 in it and Save the changes.
• I deliver a change set in Stram1
• I am go to TeamArtifact -->Source Control-->Stream2-->Track in Pending Change.

And the  change set  doesn't appear in outgoing of  Stream2 

Do you have any idea?
