Problems with 'Route to Label's

In this case the message flow is attempting to use a label that it does not recognize. There can be a number of reasons for this:

• The label may have been misspelled - either when it was defined or when it is being used. The resolution to this is to ensure that the spelling is consistent wherever the label is declared and used.
• The label may be correct but is invisible to the current artefact. Find out which Action or Flow that the label is defined in and make sure that the Action or Flow is visible to the artefact that is using it e.g. by placing the action where the label is defined on the surface of the flow that is using it.
• The Action or Flow that defines the label may not have compiled correctly and is therefore not being included in the action or flow that is using it. Check that there are no errors in the artefact that defines the Label, or in the enclosing artefacts.
