Answer 1

Können Sie das folgende versuchen zu optimieren? Sie müssen keine Maßnahmen erstellen, um Dimensionsbeschriftungen zurückzugeben. Und ein NON EMPTY sollte es durch Rücksendung nur Kombinationen von Dimensionen beschleunigen, die Sinn machen (Kombinationen mit Num des Protokolls Ich gehe davon aus):

SELECT NON EMPTY (([DimPatient].[Patient Key].[Patient Key], 
        [DimPatient].[Full Name].[Full Name], 
        [DimPatient].[Age].[Age], 
        [DimPatient].[Gender].[Gender], 
        [DimPatient].[Medical Record Number].[Medical Record Number], 
        [DimPCP].[Provider Key].[Provider Key], 
        [DimCareTeam].[CareTeamName].[CareTeamName], 
        [DimCondition].[Condition Name].[Condition Name])) ON 1 , 
{ [Measures].[Num Of Minutes] } ON 0 
FROM [NavigateCube] 
    WHERE ([DimManagedPopulation].[ManagedPopulationKey].&[5059],[DimAnchorDate].[Date Key].&[20160930])
