I have created an SSRS report and deployed it to the SQL report Server location. I want to set this report up so it executes at a certain time and creates a pdf in a network folder. However when I click subscribe I get the error "Subscriptions cannot be created because the credentials used to run the report are not stored, or if linked report, the link is no longer valid." In the credentials section of the data source of the report I am using Windows Authentication. The only way the report will execute is with Windows Authentication . I have one other report that is set up this way successfully. That report is using a different SQL database. One set up by our ERP providers. The credential setting on that report is do not use credentials. Admittedly my understanding of the security portion of SQL is weak. Any help would be appreciated. Thanks.
