The Promoted properties are in the 'Basic' tab of the message flow properties.
Try it and see.

Thanks madkak. you explained about bar over ride. it can be done once the bar file is created .
In my case , i promoted mqinput queue name property to the flow. when i try to create bar file i am getting the following error. so how i can do the bar over ride in this case please help me .
-----------------------------------------------------------------------------------
Processing file flow11.msgflow
Failed to add file flow11.msgflow to archive file.
/test111/flow11.msgflow has errors.
Please correct the errors and try again.

Thanks for reply smdavies99. Yes i can find the 'Basic' tab of the message flow properties.
Consider this scenario . Mqinput->compute->Mqoutput . if this is the sub flow and reusable in various projects. I want to assign the values for queue name for mqinput node dynamically at run time , is it possible to create a bar file without a input queue name(promoted to flow). please help me on this. |

There's a huge difference between a bar file and a subflow.
There's also an immensely large difference between a file named ".subflow" and a file named ".msgflow".
You can't deploy anything named ".msgflow" that contains an MQInput node that does not have a queue set on it's properties. |

You can't.
The best you can do is assign it at deploy time.
And as my most worthy associate points out, you can't deploy it (or indeed add it to a bar file) without any value at all.
I echo and endorse his comments on the difference between a message flow and a sub flow. Just because your flow is architecturally a common sub flow doesn't make it a broker subflow.

You can use QALIAS on the QMGR to change the queue that gets opened when the message flow starts.

Hi All ,
Thanks to everyone to give me the clear idea about the issue . now i can understand that we are doing bar override during implementation.
But in my case we are using .msgflow as a subflow . so my final doubt is whether we can use .msgflow as a subflow . |

Just one minor thing. smdavies99 is wrong when he stated that "The Promoted properties are in the 'Basic' tab of the message flow properties" if he meant that to be restrictive.
You can promote properties from other than the Basic tab of a node, and the name of the tab they are on in that node, or any other tab name that you can think of (ex: the node's name), can be used to hold the promoted properties at the flow/subflow level. The "New Group" button on the Promote Property's Target Selection pop-up lets you decide what the tab name(s) will be. |

I was just starting from an example flow I have. The OP was IMHO hardly likely to be aware of those other options at this stage in their broker education.
