We are trying to create a connection to our instance of BPC (7.5 MS SP 11.6). We are able to see the dimensions, applications, and application sets, but when a query is run, no values are retrieved. We recently downloaded the ODBO/XMLA Diagnosis tool for BPC. When we run the diagnostic tool we find that application sets, applications, dimensions, hierarchies, levels, and measures all validate, however members returns an error of "object reference not set to an instance of an object" - "No member in level [Account].[H1].[LEV11] is available."
The second error is no doubt a result of the first error. At first we felt that the issue we were having was a BO issue, however after running this tool it appears that there is an issue with the application structure or configuration that isn't allowing the member dimensions to be passed back through the XMLA connection.
