MQSeries.net :: View topic - Auto-generating fields thru MRM

Let say I have an XML message coming in as...

<XML>
<B>abc</B>
</XML>

I want to convert this XML to fixed format, so I'm using MRM. However in my MRM, I defined it as...

FieldA: max length = 3
FieldB: max length = 3

The reason is because I want my output message to be ' abc' (notice the 3 empty spaces in front of 'abc'). However, MRM will not automatically generate a field not found in the input message, instead, it will throw an exception.

I understand that if my input message is...

<XML>
<A></A>
<B>abc</B>
</XML>

Then my flow will work and my output will be ' abc', but this is just an example. In reality, my output message consists of dozens of fields which is not found in the input message, so it is not feasible if I am to manually define all the extra fields in a compute node, although it can be done.

When a message is parsed from xml to mrm (or vice versa), WMQI has the ability to pad empty spaces in a field, but does it has the ability to generate fields which is not found in xml but in the mrm?

Thanks all!
