Central Master Data DSO

Question

Hello everybody,
I'am building up an EDW and actually have some problems on loading some master data in a DataStoreObject on the harmonization layer.
I try to explain the szenario with an example:
DataSource 1 (Sorts of icecream):
ID (let's say I have 20 sorts of Ice -> So the ID would have an range of 1-20)
Text
ColorID (ID for the color of the icecream, let's say there are five different colors)
example
ID: 1
Text: Vanilla
ColorID: 1
DataSource 2 (Colors of the icecream):
ColorID (1-5)
Text
example:
ColorID: 1
Text: yellow
Problem
On the harmonization layer, I want to have a DSO with the following structure:
ID (1-20; Key)
ColorID (1-5; Key)
Text (Sort of Icecream)
Text (Color)
example:
ID: 1
ColorID: 1
Text: vanilla
Text: yellow
The problem is, that he is always writing two rows for values like in the example. Of course understand why: The Color don't have the ID (Sort of the IceCream) as a key. So the Systems is doing the following:
ROW 1
ID: 0
ColorID: 1
Text:
Text: yellow
ROW2
ID: 1
ColorID: 1
Text: vanilla
Text:
After I long way of trying I try to find an answer on this way.
Thank you in advance!!
P.S.
Rule on the harmonization layer: No InfoObjects with MasterData are allowed!

I'm guessing that you have two transformations right now, one from DS 1 to the DSO and one from DS 2 to the DSO, right?
To do this right, you need only one transformation from DS 1 (flavors) to the DSO. In the end routine of that transformation, you can look up the corresponding text for the color and populate the DSO field.
Another way to do this would be to give the color infoobject text and you can load DS 2 into the color iobj text instead of to the DSO. You could also drop the flavor text from the DSO and make it text of the flavor iobj. This is the recommended approach especially if you may need to translate your texts to other languages in the future.
