Hi All,

I am new to MB and I am writing a code where I have to access a field in usr header. The corresponding code I am using here is :

"SET type=InputRoot.MQRFH2.usr.Transaction_Type;"

However, when the flow runs , it is not accessing the value from usr header and "type" variable still remains as blank.

Also I am using RFHUTIL to add the "usr" header :

1)Under RFH Tab and V2 column, I am selecting the "usr" checkbox.

2)Under usr tab I am entering the following text as a part of usr header :

<Source>Source2</Source>
<Transaction_Type>Invoice<Transaction_Type>

Kindly Assist.

Thanks in advance

If you use usertrace, the output log will tell you exactly which element in the

Code:

SET type=InputRoot.MQRFH2.usr.Transaction_Type;

is failing.

However I suspect that you may not be setting up RFHUTIL correctly in the first place.
The MQMD.Format must tell MQ that there is an RFH2 header to follow.
Then the RFH Format field should be set to MQSTR to tell MQ that what follows is the message payload.

A good tip is to put a Trace Node after the MQUnput node, set the pattern to

Code:

${Root}

and once again use usertrace and you will easily see how the input message is being parsed by the input node.

Give it a try. Learning to use usertrace at this stage will save you a lot of time and trouble later on. There are limits to what the debugger can and can't do.

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