Translation Rules

Transformation Rules***

You have a couple options.  When bringing in the account field at the data source level you could:

1) Concatenate account with function (so bring in both the account column with an underscore then the function column to the account field (function would go to function as normal at the data source level), something like 56789_COGSFunction and 56789_SGAFunction.  Then in the account mapping you can do one for one or mask so that 56789_COGSFunction goes to 56789C and all else or specifically 56789_SGAFunction goes to 56789G.

2) Or you could bring account in to account and function in to function at the data source level and then in the account dimension, use a composite mapping that says something like:

A#?????:Ux#COGSFunction goes to A#?????C

A#?????:Ux#SGAFunction goes to A#?????G

Composite are when you need to leverage two fields (e.g. account and function) in the mapping of one field (e.g. account).  But they are a slower mapping than a 1:1.

I woudl probably lean towards #1 since handling bringing in both fields at the data source level on import, may make for easier 1:1 mappings in transformation.

But either option should work.

In the cases where you can describe how you want the maps to work by referring to another dimension's target values, that is when you should think about mapping based on the target values. You will need a conditional rule for this and GolfStream has an example:

Imports System

Imports System.Collections.Generic
Imports System.Globalization

		Public Function Main(ByVal si As SessionInfo, ByVal globals As BRGlobals, ByVal api As Transformer, ByVal args As ConditionalRuleArgs) As Object
			Try
					
				'Grab the target account value				
				Dim account As String = args.GetTarget("A#")   
				
				'Assign the flow member based on the first character of the target account
				Select Case Left(account,1)
					Case "1","2","3"
						Return "End_Inp"
					Case Else
						Return "None"
				End Select
				
			Catch ex As Exception
				Throw ErrorHandler.LogWrite(si, New XFException(si, ex))
			End Try
		End Function
	End Class
End Namespace

In your case you will want to look up the Target value (ie already mapped) of the FCT member and then get the first character of the account. It looks like the account naming is similar between the source and the target. I would add this as a Mask map that processes near the beginning of the Mask maps. And then you need to check the Transformation Sequence of the dimensions to make sure the FCT dimension is processed before the Account dimension. Cubes | Integration tab | Transformation Sequence
