Hi,
I have written a simple XML to COBOL transformation message flow in MB6. I am getting the following error, when I run the debugger.
BIPv600
" An attempt was made to parse/ write but no descriptor was loaded for CWF worker. "
Any idea, where exactly I am going wrong?
TIA
Saurabh |

Did you define a message set?
Did you set the relevant info on the OutputRoot.Properties?

Thanks for your response.
Yes. I have defined a message set and I have also set OutputRoot.Properties.
I have set MessageSet, MessageType and MessageFormat. Do I need to set any other field? |

Well the Output Tree needs to match the message as declared in the Message Set... oh yeah and the parser should be MRM

This message is issued when the MRM parser cannot find the specified physical format in the specified message set. So...check that you have specified the message set and message format accurately.
And if you want a better error message, take a user trace. |

fjb_saper - How do I set the parser to MRM in MB6. I have set the message format to CWF.
kimbert - As suggested by you, I tried setting up a user trace. I am unable to start trace command because the environment variables are not set properly. I need to set the following environment variables - MQSI_UTILITY_TRACE and MQSI_UTILITY_TRACESIZE with some value. Also I am not sure how environment variables are set. Please suggest. |

If you are using the message broker command console, you do not need to set any environment variables. You just need to issue mqsichangetrace ( to collect the trace ) followed by mqsireadlog ( to extract the trace ) and mqsiformatlog ( to format it ).
But before you do that, check that you have specified the message set and physical format name correctly. That is the most likely error, and you don't need user trace to check that. |

Either in the MQInput Node or in the OutputRoot... depending on which side of the flow the message should be in MRM/CWF1 format...

Thanks Kimbert and fjb_saper for your inputs. I created the message set again and it worked. I had probably not added the wire format to the message set, when I first created it.
I have one question though. Whats the difference between CWF / CWF1 and CWF2?
Thanks again. |

Place holder for convention? In fact you can give the same message 3 different wire formats by changing field properties on the specified wire format (CWF, CWF1, CWF2)...
