Deleting a workflow Instance in Microsoft Dynamics AX 2012
I’ve been wanting to write a tutorial explaining the tables involved in a workflow and how to delete an instance if necessary (e.g. when a major fault or data inconsistency occurs), however it seems Colin’s Dynamics AX 2012 blog beat me to it and he did a superb job at that, check it out here
Dynamics AX Workflow Wanderings 
Links to Colin’s website and post are not working. But, there are nice travel photos there of a trip to Antartica. :-).
Can you re-provision the same information about canceling an AX workflow?
Thanks.
