Copy data from another cube (with different dimensionality)

Is there an easy way, to copy data from one cube to another (with different dimensionality)

Yes, there are some function in the financial business rules api to support this:

api.Data.ConvertDataBuffer
api.Data.ConvertDataBufferExtendedMembers

With the first function, you define the mapping between the cubes on your own, the second one uses the extended dimension definition for the mapping.

    Here is a sample for ConvertDataBufferExtendedMembers

    Dim sourceDataBuffer As DataBuffer = api.Data.GetDataBufferUsingFormula("cb#CubeName:A#All")
targetDataBuffer = api.Data.ConvertDataBufferExtendedMembers("CubeName", "ScenarioName", sourceDataBuffer)
Dim expDestInfo As ExpressionDestinationInfo = api.Data.GetExpressionDestinationInfo($"C#{api.Pov.Cons.Name}")
	
api.Data.SetDataBuffer(targetDataBuffer , expDestInfo)

    Here is a sample for ConvertDataBuffer

    Dim dataBufferConvInfo As New DataBufferConversionInfo
	
Dim dataBufferConvDimInfo As New DataBufferConvDimInfo
Dim dataBufferMapItem As New DataBufferConvMapItem(DataBufferConvType.MapSourceMembersToFirstDestMember, "UD1#Top.Base",  "UD1#None", 1)
dataBufferConvDimInfo.MapItems.add(dataBufferMapItem)
dataBufferConvInfo.UD1Info = dataBufferConvDimInfo

dataBufferConvDimInfo = New DataBufferConvDimInfo()
dataBufferMapItem = New DataBufferConvMapItem(DataBufferConvType.MapSourceMembersToFirstDestMember, "UD2#Top.Base",  "UD2#None", 1)
dataBufferConvInfo.UD2Info = dataBufferConvDimInfo
	
Dim sourceDb As DataBuffer = api.Data.GetDataBufferUsingFormula("cb#CubeName:A#All")
Dim targetDb As databuffer = api.Data.ConvertDataBuffer("CubeName", "ScenarioName", dataBufferConvInfo, sourceDb)
	
Dim expDestInfo As ExpressionDestinationInfo = api.Data.GetExpressionDestinationInfo($"C#{api.Pov.Cons.Name}")
	
api.Data.SetDataBuffer(targetdb, expDestInfo)

      Hi Christian,

      I am trying to run the ConvertDataBuffer but receive an error when executing the Data Management job. The error says "Error processing script 'C#USD'." I have tried updating $"C#{api.Pov.Cons.Name}" to reference C#Local, but that still errors out. Did you run into this error as well?

      Hi

      Consolidation isn't a databuffer dimension but a dataunit dimension. So you only can set it to the api.pov.cons.name member of a financial business rule. So if api.pov.cons.name is 'elimination' and you set the destination info to 'local', or 'USD', you will get an error message.

      So if you embedded the code in a member formula or cube business rule, you're not only calculating it on local, but also during translation, elimination, or share calculation and it will trigger an error.

      I hope this helps

      Cheers

      Good stuff - but where do we find more documentation on these functions? As LeeB also ask's, I need to map from one Ud to another UD in the target cube. Seems there's an option to use MapSourceMembersToDestMembers, but how this works is not clear. /Cheers
