Hi, I tried to create cross joins betweens views and it worked fine for me by following the below steps * In the Model tab, drag and drop the views ‘view_a’ and ‘view_b’. * In the Join Conditions tab  choose  “Add cross join” to define a cross join between views. * Select the required fields to display in the output tab and execute the view. For more information on defining joins refer the [ Creating join views]( section of the Virtual DataPort Administration Guide. Hope this helps you!

Hi, It works for me in all the cases. In your case, I recommend you to enable VDP-requests.log file, to view the queries sent to the Server. Using which you could view the executed queries and the one which returns error. I would do the following steps to enable requests log, * Change the log category ‘com.denodo.vdp.requests’ to 'INFO' level by calling the LogController Stored Procedure in the VQL shell as, CALL LOGCONTROLLER('com.denodo.vdp.requests', 'INFO') * The request information sent to the server are logged in to the directory <Denodo-Home>\logs\vdp\vdp-requests.log. Hope this helps you!
