Hi, I was able to perform an inner join using 28 views in my environment, it worked fine for me without any errors. In this situation, I would perform the following checks in order to get more information. * Check the server logs in the data source side * Check the Execution Trace under the Query Results tab of the join view * Check the vdp.log file located under the directory <DENODO_HOME>/logs/vdp In the Execution Trace, you may look for the errors that will help you to understand this issue. I found the relevant info in the following user manual. * [Execution Trace of a Statement]( Hope this helps!
