SSAS: programmatically & permanently create calculated member

Question

I'm trying to permanently create a calculated dimension member using a MDX ADOMD command from C# code. The following MDX script creates the member but it's only available for the current session.

CREATE MEMBER [Cube].[Dimension].[Hierarchy].[My Member Name] as 
    Aggregate({
        [Dimension].[Hierarchy].[Level].&[1], [Dimension].[Hierarchy].[Level].&[2], ...
    })   

How to permanently create it?

Answer 1

Never tried it, but I found some AMO code that appears to do this, it's loading the current MDX calculation script from the cube, adding to it, then posting it back.

Dim objServer As Server
Dim objDatabase As Database
Dim strDataBaseID As String
Dim objCube As Cube
Dim objMdxScript As MdxScript
Dim objCommand As Command
Dim strCommand As String
objServer = New Server
objServer.Connect(“localhost”)
objDatabase = objServer.Databases(“Adventure Works DW 2008″)
strDataBaseID = objDatabase.ID
If objDatabase.Cubes.Count > 0 Then
objCube = objDatabase.Cubes(“Adventure Works”)
If objCube.MdxScripts.Count > 0 Then
objMdxScript = objCube.MdxScripts(“MdxScript”)
”objMdxScript = objCube.MdxScripts(0) 
Else
objCube.MdxScripts.Add(“MdxScript”, “MdxScript”)
objMdxScript = objCube.MdxScripts(“MdxScript”)
End If
objCommand = New Command
strCommand = “CREATE MEMBER CURRENTCUBE.[Measures].[Multipy Measures By 20]“
strCommand = strCommand & ” AS [Measures].[Internet Sales Amount] * 20, “
strCommand = strCommand & ” VISIBLE = 1 ; “
objCommand.Text = strCommand
objMdxScript.Commands.Add(objCommand)
objMdxScript.Update()
objCube.Update()
End If
objServer.Disconnect()

I use AMO elsewhere, but haven't used it like this, so do report back on results :)
