Hi friends,
My flow is
Mqinput ->Compute ->Mqoutput.
Mqinput will receive messages from datapower and it has to concatenate all the messages in compute node until one element Zstatus in themessage header becomes TRUE.
How to do concatinate all the messages receiving from datapoweer?Please give me a suggest approach

two options come to mind
1)
Write messages to a temporary queue
When you get the 'end' message
read all message and build your concatenated message

OR
2)
use a table (my preferred method)

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions.

I am using Mq get node to hold the messages.But it is not storing all the messages which ever i am sending.
Is there any other properties which i should set in the mqgetnode?

The MQGet node DOES NOT STORE THE MESSAGES

They are stored on a queue which is read by the MQGet node.

Have you looked at the messages on the Queue? Are they all there? Is all the data there?

Actually the control is not passing from mqgetnode.I have set below properties for mqgetnode still I am not able to process the message from MQget node.

Properties :
Quename - GET
Generate mode - Message and localenv
copy message - copy entore message
copy local environment - coopy entire local environment
Output data location - OutputRoot.

Can you look again at my questions and at least try to answer them

Before you can read the messages with the MQGet node they have to be on the queue. Once you are satisfied that the messages are being written to the queue correctly (what sort of transactionality are you using? are the fully commmitted?)

Then move onto the reading. Put a timeout on the read and see if you get a 2033 error. If so then go back to the writing and make sure that everything your write is committed.
You can't read it if it has not been committed.

Ya..i am sorry. Actually i didnt get the message to the queue read by MQGet node.
I am doing debug and control gets terminated once it reaches to MQgetnode.

There are two separate but related issues here.

1) You didn't get the message written to the queue correctly
2) You can't read the message

Use UserTrace. It is much easier to find out where things go wrong.
Why does control get terminated at the MQGet node? What is the error?
