SSAS计算得出的度量，仅显示特定尺寸值的值

Question

I have a calculated Measure in my SSAS cube, which I want to calculate only for a group of dimension members and for rest it should be zero. In The following image I want MTDOccupancy dimension to work only for Account Groups for Rooms, rest related to food should show zero for this field.

following is the simple MDX which I am using for MTDOccupancy measure

([MTDQuantity]/[MTDAvailableRooms])*100

Answer 1

You can change the measure to something like the following:

IIF(
    LEFT([Account Group].[Account Group].currentmember.member_caption,5) = "ROOMS"
  ,([MTDQuantity]/[MTDAvailableRooms])*100
  ,NULL
)

I have guessed this dimension/hierarchy combination [Account Group].[Account Group]. ... [Account Group].[Account Group]. ... - you will need to change this to reflect the names used in your cube.

Answer 2

Please do it as a scope statement for performance reasons. The following will get evaluated the first time someone connects to the cube vs the LEFT running in every cell at report time:

Create member CurrentCube.[Measures].[My Calc] 
as null
,format_string="0.0%";

scope(Filter([Account Group].[Account Group].[Account Group].Members,   LEFT([Account Group].[Account Group].currentmember.member_caption,5)="ROOMS")); 
   [Measures].[My Calc] = iif(MTDAvailableRooms=0,null,([MTDQuantity]/[MTDAvailableRooms])); 
end scope;
