Need help with ranking / finding max category

[badger123]

Hi all, I just can't seem to figure out how to do this... please help! 

I would like to display in a table visual ID and Category as columns, where the Category is that with the highest summed volume based on the Text selected. 

Desired output in table visual:

ID	Category
Item One	C
Item Two	D

Table 1: 

ID	Text	Category
Item One	text one	A
Item One	text two	A
Item One	text three	A
Item One	text four	B
Item One	text five	B
Item One	text six	B
Item One	text seven	C
Item One	text eight	C
Item One	text nine	C
Item Two	text ten	A
Item Two	text one	A
Item Two	text two	C
Item Two	text eleven	D
Item Two	text twelve	E

Table 2:

Text	Volume
text one	10
text two	20
text three	30
text four	40
text five	10
text six	20
text seven	30
text eight	90
text nine	100
text ten	50
text eleven	200
text twelve	10

Assuming Table1 (Many side) is related to Table 2 (One Side) using Text Column

Try this Measure

Measure =
CONCATENATEX (
    TOPN (
        1,
        CALCULATETABLE ( VALUES ( Table1[Category] ) ),
        CALCULATE (
            SUM ( Table2[Volume] ),
            CROSSFILTER ( Table1[Text], Table2[Text], BOTH )
        ), DESC
    ),
    [Category],
    ","
)
