Creating the exposure difference in two tables

Hi dejanzoric ,

Base on your provided data, what's expected result? Is the below table your expected result? If yes, how do you get these values especially the values with red line or circle?

I created a sample pbix file(see the attachment), please check if that is what you want.

1. Create a dimension table as below

Table = DISTINCT ( UNION ( VALUES ( 'Table 1'[ID] ), VALUES ( 'Table 2'[ID] ) ) )

2. Create the measures as below

Amount1 = 
VAR _ids =
    SELECTEDVALUE ( 'Table'[ID] )
RETURN
    CALCULATE (
        SUM ( 'Table 1'[Amount] ),
        FILTER ( 'Table 1', 'Table 1'[ID] = _ids )
    )

Amount2 = 
VAR _ids =
    SELECTEDVALUE ( 'Table'[ID] )
RETURN
    CALCULATE (
        SUM ( 'Table 2'[Amount] ),
        FILTER ( 'Table 2', 'Table 2'[ID] = _ids )
    )

Difference = [Amount1]-[Amount2]

3. Create a table visual

Best Regards
