Merge text values from different rows into one row based on value in another column

[Hayleysea]

Hi there, how can I achieve the below data transformation? The reason is I have two separate table with the same data structure that I need to compare using a matrix visual. At the moment the Type value from the first table splits the type into 3 different rows and then the type value from the second table is repeated each time so it looks like output table below. 

From:

Name	Type
Bob	A
Bob	B
Bob	C

To:

Name	Type
Bob	A B C
Bob	A B C
Bob	A B C

Current output:

Name	Table 1	Table 2
Bob	A	A
		B
		C
	B	A
		B
		C
	C	A
		B
		C

Desired output:

Name	Table 1	Table 2
Bob	A B C	A B C

Hi @Hayleysea,

I'd like to suggest you write a measure formula to use a current category to look up correspond records and merge them into one and use it on matrix. It will show the expected result as you wanted.

measure =
CALCULATE (
    CONCATENATEX ( VALUES ( Table1[Type] ), [Type], " " ),
    FILTER ( ALLSELECTED ( Table1 ), [Name] IN VALUES ( Table2[Name] ) )
)

@Hayleysea , If you have common dimension Table  Name joined with Table A and Table B, Then this should work.
