I've created the OLAP template following all the steps correctly in the SpagoBI studio. While uploading the XML template, I'm getting the following exception:
it.eng.spagobi.sdk.exceptions.SDKException
If you look at the xml produced by the Studio with a text editor you may probably notice that the hasAll tag is uncorrectly generated. If this is the problem you are facing, it's a known bug. You can edit the xml manually and then redeploy the template or wait for the patch to be published.
