Hi All,
I got below information from IBM Information Center for Finalize clause which can be used in PROPAGATE statement.
FINALIZE clause
Finalization is a process that fixes header chains and makes the Properties folder match the headers. If present, the FINALIZE clause allows finalization to be controlled.
This clause is only applicable to the Compute node (it has no effect in a Database node).
The Compute node allows its output message to be changed by other nodes (by the other nodes changing their input message). However, a message created by a Compute node cannot be changed by another node after:
It has been finalized
It has reached any output or other node which generates a bit-stream.
I did not get exactly how it affects the output message and what is exactly meant by fixing the header chains and finalization process ?
Can you please help me to understand this stuff ? |

The main point is that once a node finalizes a message tree, the message flow can no longer modify the message tree.
A secondary point is that during finalization, the contents of the Root.Properties sub-tree are synchronized with related fields in the other Root header sub-trees.
The default behavior is to finalize OutputRoot when propagating it. So, a modifiable OutputRoot tree in one node becomes an unmodifiable InputRoot tree in the next node. The next node is still free, though, to make a copy (e.g. "SET OutputRoot = InputRoot;"), and modify the copy.
The FINALIZE clause allows a node to propagate its OutputRoot without finalizing it. However, the circumstances where this might be preferable are somewhat unusual. Don't use the FINALIZE clause without good reason, nor without understanding how it affects the message flow behavior, particularly during partial roll-backs. |

Thank you for your reply.
To check the theory, I tried to modify InputRoot in Compute node in two ways.
1. I put statement something like -
SET InputRoot.XMLNSC.Test.Item = NULL ;
I got compilation error which was expected.
2. Then I tried like this -
DECLARE inRef REFERENCE TO InputRoot.XMLNSC;
SET inRef.Test.Item = NULL;
And it worked.. No Compilation Error.. No Deployment Error..
And I verified, the field actually got deleted from InputRoot.
So whether message tree is finalized or not, I was able to modify it using reference. So is there any practical use of this clause other than fixing / synchronizing Properties tree ? |

You might want to open a PMR with IBM. I don't think they intended to let you modify the InputRoot tree even if referenced...

There are two possible interpretations here.
1) That you exploited a bug in how references are handled.
2) That you did not actually delete anything in InputRoot - your verification steps did not show what you thought they showed.
Secondly, I believe that a finalized tree is more locked down than rekarm01 thinks it is. But I'll also repeat the advice that rekarm01 gave - don't use FINALIZE unless you know exactly why you are doing it. |

Please explain. The message flow cannot modify a finalized message tree. What's more "locked down" than that?  |

Well, what I was thinking was that it was not possible to copy a finalized tree, somehow.
But I am informed that I am generally entirely off base in this thread, so please ignore what I've said and carry on. |

cmon somebody please solve this problem , i tried modifying the message , mqmd and properties folder after using this clause in a compute node. But all got changed .
then i used to propagate statements in th same compute node:
SET OutputRoot.XMLNSC.message.msg1 = 'number one';
PROPAGATE TO TERMINAL 'out' FINALIZE DEFAULT DELETE NONE ;
SET OutputRoot.XMLNSC.message.msg1 = 'reassigned';
PROPAGATE TO TERMINAL 'out1' ;
even after this msg1 got changed in the second statement |

This used to be true in mqsi 2.1 but as from V5 input message trees are modifiable, including InputRoot. |

dip reopened an old thread, rather than creating a new one, so the quote you're responding to is from 2009.
Based on my fuzzy recollection, finalized trees are not modifiable; unfinalized InputRoot trees are modifiable, but not through the InputRoot correlation id.
However, I have not had a reason to more thoroughly test either of these claims lately, so don't rely on them without further verification.

Please describe more clearly what you are trying to do, what you have done, and the difference between your expected and actual results. Posting the relevant portions of Trace node output or usertrace may also help. |

I stand by my quote: Input trees are modifiable since v5 regardless of finalized or not.
I may be responding to a quote of 2009, but it is still true ! |

What problem?
| dip wrote: |

So you create (and finalized) a message and sent it through the Out terminal. You then updated the OutputRoot.XMLNSC.message (retaining all the other details through the use of DELETE NONE) and sent that through the Out1 terminal. Why are you surprised (and apparently alarmed) that you got 2 different messages downstream?

Okay. Please explain why the Knowledge Center seems to contradict that:
| Quote: |
| ... a message created by a Compute node cannot be changed by another node after it has been finalized, ... |

'' from trace node 'test.Trace'.
The trace node 'test.Trace' has output the specified trace data.
This is an information message provided by the message flow designer. The user response will be determined by the local environment.
2016-06-01 05:52:56.315976 8924 UserTrace BIP4067I: Message propagated to output terminal for trace node 'test.Trace'.
The trace node 'test.Trace' has received a message and is propagating it to any nodes connected to its output terminal.
No user action required.

You will see that the first compute node receives an xml message with value = '123456' and propagates with FINALIZE.
The second compute nodes changes the value to 99999. |

sorry for opening an old one..... "newbie" 
case 1:
i tried
mqip -> cn1 -> cn2 -> mqop
in cn1 : SET OutputRoot.XMLNSC.message.msg1 = 'number one';
PROPAGATE TO TERMINAL 'out' FINALIZE DEFAULT DELETE NONE ;
in cn2 : SET OutputRoot.XMLNSC.message.msg1 = 'reassigned';
the message got changed in cn2. I tried the same with mqmd fields too but they also changed. Anyways , why this is happening I understood, but....
case 2:
mqip -> cn -> mqop
in cn :
SET OutputRoot.XMLNSC.message.msg1 = 'number one';
PROPAGATE TO TERMINAL 'out' FINALIZE DEFAULT DELETE NONE ;
SET OutputRoot.MQMD.Transactional = FALSE;
SET OutputRoot.XMLNSC.message.msg1 = 'reassigned';
PROPAGATE TO TERMINAL 'out1' ;
RETURN FALSE;
Now according to knwldge cntre, finalize should make the msg constant. So, after the first propagate statement, so how is it modifying the same message and even the header got changed??? |
