I am using Tableau version 8.0.0. When I publish the report in Live server I get the following error **"TableauException: Field '[ACCOUNT_SCHEDULE_FACT].[DATE_DM]', which is included in a join clause, does not exist. Unable to connect to the server ". I have verified that the column DATE_DM exists in table ACCOUNT_SCHEDULE_FACT. The server is up and running. The join condition in the report has been verified even for case sensitive issue. However when I publish the same report in Development Server or when I check it in desktop (without publishing) it does not throw any error and works smoothly. The custom SQL from tableau has been executed in our SQL server database and it returns the correct number of rows. Can somebody point out why this error is occurring or whether there is any workaround for this problem?
