You have now defined everything needed for error handling using workflow.
To verify that everything is correct, in the ALE Development menu, choose (BDM6).
The line containing your process code should appear white if everything is OK, yellow if you are not using an application object type and everything is OK, and red if at least one setting is incorrect. (These colors assume the default color settings.)
To see details, double-click on the line containing your process code.
Process codes and event linkages are client-dependent, so make sure you carry out the check in the correct client.
