Is there an easy way, to copy data from one cube to another (with different dimensionality)
Solved! Go to Solution.

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

As an alternative to
api.Data.SetDataBuffer(targetdb, expDestInfo)
you can use these lines, it make the pov situation obvious
Dim povString As String = $"E#[{api.Pov.Entity.Name}]:C#{api.Pov.Cons.Name}:S#[{api.Pov.Scenario.Name}]:T#{api.Pov.Time.Name}:V#{api.Pov.View.Name}"
'Save the data buffer
api.Data.FormulaVariables.SetDataBufferVariable("resultBuffer", resultBuffer, True)
api.Data.Calculate(povString & " = $resultBuffer", True)
Cheers
