If DemandTools V does not have the file to read, it won't be able to recognize the full scenario.</P> <P>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&nbsp;<EM><STRONG>did</STRONG></EM> select the file &amp; are receiving the error, I would suggest opening a request with our support team by <A href="https://mycommunity.validity.com/t5/custom/page/page-id/SupportPage-CreateNewTicket-v2?=undefined&amp;formid=263508" target="_self">filling out this form</A>.</P> Thu, 18 May 2023 15:40:32 GMT https://mycommunity.validity.com/t5/demandtools/migrating-scenarios/m-p/839#M427 JonG_Validity 2023-05-18T15:40:32Z
