I have searched for a simple description of how to accomplish adding a field to an existing MRM message. In the process I have created a second message definition in the same message set with the added field. I am using a compute node to do as follows:
Set OutputRoot = InputRoot;
Set OutputLocalEnvironment = InputLocalEnvironment;
Set OutputExceptionList = InputExceptionList;
Set OutputRoot.Properties.MessageFormat = 'CWF';
Set OutputRoot.Properties.MessageSet = 'N03LEN4002001';
Set OutputRoot.Properties.MessageType = 'brand-vehicle';
IF OutputRoot.MRM.mtype = 'CYCLE' THEN
CREATE FIELD OutputRoot.MRM.brand;
Set OutputRoot.MRM.brand = 'Harley';
PROPAGATE TO TERMINAL 'out1';
END IF;
...

brand-vehicle is the definition file name of the output message definition file.
I am getting errors that have me go in circles.
parsing the input correctly as in:
(0x01000021:Name+):MRM = ( ['mrm' : 0x806e8f0]
(0x0300000B:NameValue+):wheels = '.FOUR' (CHARACTER)
(0x0300000B:NameValue+):seats = '..two' (CHARACTER)
(0x0300000B:NameValue+):engine = 'VTWIN' (CHARACTER)
(0x0300000B:NameValue+):fuel = '93OCT' (CHARACTER)
(0x0300000B:NameValue+):mtype = 'CYCLE' (CHARACTER)
)
)

Error is as follows:

I am trying to understand what is meant by 'An Attempt was made to parse/write but no descriptor was loaded for the CWF worker' but can not figure out what descriptor needs to be loaded?
Please advise, thanks

Did you deploy the message sets?

Why not just add the field to the existing message? Why create a new one?

I suspect the error is because the code is using the message which doesn't contain this new field so fails creating the bitstream when it encounters it. Unless you changed the code as well which is impossible to tell from your post.

Which would be easier to read if the code was in [ c o d e ] tags.

Then that is probably your problem. The 'messageType' property must be set to the name of a message in the specified message set.

Thank you all!!!!
It looks like this issue has been resolved simply by providing the proper definition file name for the output format, it is listed under the "Messages" folder and it had "msg_" in front of the name. Also since the format remained MRM these lines:
Set OutputRoot.Properties.MessageFormat = 'CWF';
Set OutputRoot.Properties.MessageSet = 'N03LEN4002001';
were removed from the ESQL.

The exception list contains a very short, and not very useful error message.
If you had looked in Windows Event Viewer you would have seen the entire message. It would probably have told you to check the MessageType property.

It's not a file name, as I explained in my previous post. Sloppy terminology leads directly to bad solutions, in my experience.
