Log Message from the passing message
Hi,
Environment:
IBM message Broker 6.1
IBM Websphere MQ 6.1
Scenario: Trying to parse a file (Non-X12 format) using File Input node, configured with message set and message definition, in a message flow.
Getting this error, when I put the file. Could any one give your valuable opinion about this error? Here is the error.
Thanks,
Vairavan C

I'd say the input message is longer than the message set says it is.

Thanks for the response. Also I have noticed in the Application errors. It says
1. An error occured in parser 'Root' while parsing the field named 'MRM' on behalf of node' FileInputNode'. The data beeing parsed was "Stream Based Buffer - no stream data read in yet."
2. A Custom Wire Format error has occured. The message bit stream is smaller than expected.
Just check with these errors too. Any suggestion is highly valued and appreciated.
Thanks,

First and obvious thing is to check the file contains what you think it does and is exactly the same format as the message set (especially in terms of length). Does the file have optional or repeating elements which can vary it's length? If so, does the message set correctly code for those?
Also check for bounds. Does the message set indicate you can have 1-5 occurances of a field, and there are 6 in the file? Are the fields at the end of the file optional, but the message set believes them so be mandatory?
