I'm having a problem with trapping errors in a message flow. When a XML message throws a user exception it rolls back to the failure terminal of the input node correctly and is written to the error queue. However, I need it to roll back to the catch terminal also. The catch terminal is wried to a standard error processing sub-flow that eventually sends an e-mail notification. This process works fine if the error is generated in one of a number of other sub-flows (mostly db errors).

Is there a way to have a user generated error process through the catch terminal also.

MQSeries = 5.2.1
WMQI = 2.1 CSD 3

Code:

SET OutputLocalEnvironment.Destination.MQDestinationList.DestinationData[1].queueName =

CASE
When InputRoot.XML.Table.FUNCTION = 'INVENTORY_ITEMS' Then
'MMS_B2B_ITEMS'
When InputRoot.XML.Table.FUNCTION = 'MATERIAL_MISC' Then
'MMS_B2B_MATERIALS'
When InputRoot.XML.Table.FUNCTION = 'MATERIAL_EXP' Then
'MMS_B2B_MATERIALS'
When InputRoot.XML.Table.FUNCTION = 'MATERIAL_SO' Then
'MMS_B2B_MATERIALS'
When InputRoot.XML.Table.FUNCTION = 'LABOR_ACTUALS' Then
'MMS_B2B_LABOR'
When InputRoot.XML.Table.FUNCTION = 'CHART_OF_ACCOUNTS' Then
'MMS_B2B_COA'
When InputRoot.XML.Table.FUNCTION = 'LABOR_HOURS' Then
'MMS_B2B_LABOR'
When InputRoot.XML.Table.FUNCTION = 'EMPLOYEE_INFO' Then
'MMS_B2B_EQDB'
ELSE
'XXXXX'
END;

IF OutputLocalEnvironment.Destination.MQDestinationList.DestinationData[1].queueName = 'XXXXX'
THEN
Throw user exception message 2591 values ('Invalid Function Code in data');
END IF;

By default your message should rollback to catch terminal first. How did you verify that this message is not going to the "catch" terminal of the MQInput node?
To verify this, remove your sub-flow from the catch terminal and attach a simple trace node, which will write the data to some file.
