Query for unique values in two columns.

Hello everyone!

 

I am relatively new to Power BI, specifically to using Power Query. I have multiple source files, which all use a certain code to distinguish certain budgets. These codes have a short description, which is always the same for the code. The data looks like the sample below. 

 

In order to define the relationships between my different sources, I'm trying to create a 'master' tab in Power Query, that contains all unique codes and descriptions. How can I do this? I know about List.Distinct, but that doesn't work if I want to do it for two columns. If I try do define relationships now, it doesn't work because the codes are not unique. 

 

The second table shows what I'm trying to achieve.

 

Thanks so much for helping and thinking with me!

 

What I have:

CodeDescriptionAmount
9999X1111Car parts100
8888X2222Truck parts60
9999X1111Car parts-10

 

What I want to create:

CodeDescription
9999X1111Car parts
8888X2222Truck parts
