I want to parse a fixed length mesage with mrm messageset.
Message will have body(1...n) and trailer(1..1). Last record is the trailer. Record delimeter is CRLF. I tried creating messageset but it is taking all the records as body.
Message Structure
Body (2 fields)
Name String 3 charactes
Class String 2 characters
Trailer( 2 fields)
Grade String 1 charactes
Result String 4 characters
EG Input:
ABIMA
ANUBA

There are LOTS of very similar requests here. Why don't you take a look at them and try a few things out. You will learn a lot more that way.
As you are using MRM, I take it that you are using a version pre 8.0.0.0.
for 8.0.0.0 and later it is recommended that you use DFDL for this type of work.

Your user name would suggest that you are using v8. In which case, DFDL is the best option.

I beg to differ here.
Your requirement is to produce a model that will allow you to parse bitstream against it to produce a message tree OR to parse a message tree to produce a bitstream.
The OLD (pre V8 ) method was to use a message set. Whilst you can still do that, these days the recommended method is to create a DFDL model and use that instead.
Perhaps whoever gave you this assignment should attend the V8 training so that they can find out all about the nifty new things that people like Steve Hanson and Kimbert have been working on and put into the product?
DFDL is really the way forward.
I'd like to refer the OP to a thread in this forum titled, 'And the Requirement is'.

I agree 100% with smdavies99. I have used DFDL in several customers, it is a lot easier and more powerful than MRM. If you cannot make it work, you are probably doing something wrong.
By the way, on the subject of DFDL, when are we going to get Input and OutputValueCalc ? |

- did you use the Test Parse facility to test your DFDL model?
- did you look at the DFDL Trace when trying to make your DFDL model work?
If you provide the following information:
- an example message ( simplify it if necessary )
- the DFDL xsd that you tried
- the DFDL trace that was produced by the parser
...then I can help you to get the model right.
