I have a workflow for a client that sometimes won't match either the Delivery Docket or Order Number Field. 95% percent of the time this does work. I have manually put the DD or ON in to the search criteria and it works. When I manually run the workflow, it shows a syntax error in the search string. Yet it works for most of the time.
I have attached the Workflow. I can supply more details as needed too.
p.s. rename the attached matched.wfi.jpg to remove the .jpg extension :)
