I got null for tmpWerk, but there is value for WERK when I trace flow. The issue has been with me for couple of days, Can you help me with it? Thanks in advance |

Snazzy.
Show us the line where you *call* it.

Snazzy.
Show us the usertrace.
Look, to be clear. Debugger view versus user trace view is *different*, particularly on "previous" versions of Broker. usertrace is *more reliable*.
More ... "importantly"?
You've indicated
DECLARE mq004_nls NAMESPACE 'http://www.ibm.com/websphere/crossworlds/2002/BOSchema/sap_zgq_qm_i004_mq/';
And you've also indicated
.....Q1.........................http://www.ibm.com/websphere/crossworlds/2002/BOSchema/sap_zgq_qm_i004_mq
These are *different* values.
"/" <> "". |

Also you are missing a namespace somewhere in your code:
| Code: |
| InputRoot.XMLNSC.Q1:sap_zgq_qm_i004_mq.sap_is_qals.Q2:sap_is_qals.WERK; |
Now you figure out the exact values for Q1 and Q2 (see your own and Jeff's posts), declare them as namespaces and you should be good...

Does 'WERK' have a namespace?
Your extract from the user trace stops too soon. If you read a little further it will tell you exactly how it executed that SET statement, and what the result was.
If you insert a Trace node then you will be able to compare your ESQL against the Trace node output, and see whether they match. Or you may find the same info in the Debugger, but it will be harder to paste the debugger output on this forum. |

I suspect this maybe at least part of your problem:
| Code: |
CALL QMI004DataProcess(Environment,InputRoot,OutputRoot,OutputLocalEnvironment);
CALL CopyEntireMessage(); |
Calling CopyEntireMessage() will delete everything under OutputRoot, and I'm guessing that your procedure tries to put something in OutputRoot which is then deleted. Either call CopyEntireMessage before your procedure, or just the parts of the Input message you actually need to your Output message and save some copy time...

there is no namespace for WERK.
and the next usertrace is for other information.

I didn't operate OutputRoot, I just want to save info from InputRoot into database. So I think it is not relate to CopyEntireMessage(). |

Spaces can be a valid value for WERK.
I re-arranged the data of InputRoot from usertrace, every field have value

It seems like each field has a namespace Q2, but In my project, there is no namespace for these fields. |

According to the date format in the usetrace, I *got* the value for WERK from InputRoot as following at last, But I am not clear why a namespace shoud be added before WERK, can someone help me explain it?

Really there is no namespace for WERK, it is weired!
Here is the correct code for getting value for 'WERK':
SET TMP = InputRoot.XMLNSC.Q1:sap_zgq_qm_i004_mq.Q1:sap_is_qals.Q2:sap_is_qals.Q2:WERK;
Here is the structure of sap_zgq_qm_i004_mq.mxsd

It's hard to do that using the information in this thread. You must have changed something, because a couple of posts ago you showed us a user trace where this field was clearly *not* present in InputRoot.
| Code: |
| 2010-07-20 06:28:21.209940 3652 >> UserTrace BIP2539I: Node 'com.zoomlion.esb.qm.rfc.i004.SapToQMI004.Compute': Evaluating expression ''InputRoot.XMLNSC.Q1:sap_zgq_qm_i004_mq.sap_is_qals.Q2:sap_is_qals.WERK'' at ('com.zoomlion.esb.qm.rfc.i004.QMI004DataProcess', '26.12'). This resolved to ''InputRoot.XMLNSC.http://www.ibm.com/websphere/crossworlds/2002/BOSchema/sap_zgq_qm_i004_mq:sap_zgq_qm_i004_mq.sap_is_qals.http://www.ibm.com/websphere/crossworlds/2002/BOSchema/sap_is_qals:sap_is_qals.WERK''. The result was ''NULL''. |
My next step would be to take another user trace, find the equivalent entry, and compare the old with the new.

Tip1: Insert a Trace node into your message flow, and set the pattern to {Root}. Then you won't have to scan the user trace output to find the values.
| Quote: |
| Here is the structure of sap_zgq_qm_i004_mq.mxsd |
Tip2: use [code] tags when posting trace output - then you won't need to use .... for indentation. |
