XMLA lets you connect to an SSAS (SQL Server Analysis Services) cube. It is Microsoft's way to access SSAS via HTTP.You can setup XMLA in one of three ways:
1. During the MSI installation
2. After installation by going to All Applications> ReportPortal > Setup ("C:\inetpub\wwwroot\ReportPortal\bin\XmlaSetup.exe")
3. Manually https://www.youtube.com/watch?v=tJGGyg1dDHY. After the manual XMLA setup, go to Admin > Connections and create XMLA URL type of connection with URL pointing to XMLA/msmdpump.dll
I already tried what you tell me but I can not connect, I'm working with ReportPortal 5 and SQL Express 2008, is there any other way to connect and create the olap cubes?
If you have only a sql datasource than you can use rolap reports in reportal. First make a rolap cube in reportportal than you can connect to it and make amazing interactive reports.
