Hi @AnneMargarette, I'm sorry to see that you're encountering an error when migrating your scenarios to DemandTools V - When migrating your Single Table Dedupe scenarios, be sure to migrate any and all winner/field rules associated with those scenarios at the same time. If DemandTools V does not have the file to read, it won't be able to recognize the full scenario.
If you do not have the master rule file, then I would suggest removing that from your 2.91 scenarios and migrating it after to receate the necessary rule in DemandTools V. If you did select the file & are receiving the error, I would suggest opening a request with our support team by filling out this form.
