ASO copy then load additive issue
ASO cube that is copying data into a current month then loading additively on top of this data to create a total. The problem is the load file might have a minimal amount of rows where one dim changes among the key intersections. The copied data should reflect this change. So the copy data might look like: Dim1 = X, Dim 2 = L1, Dim 3 = P1
Loaded data: Dim1 = Y, Dim2 = L1, Dim3 = P1
ASO makes it a bit trickier but is there an idea someone might have where I can "stage" the copied data somewhere & reference loaded data intersections to change copied data Dim1 to equal Y? Or is maybe SQL the best bet? It's quick turnaround so unfortunately I didn't have a ton of time to start a lot of dev so was looking for ideas.
