Lookup and Verify Three Columns on Another Table and Generate a Value
What I am trying to accomplish with no success is the following.
Table 1 (Simplified for example)
Unit Num
| A1111 |
| B2222 |
| C3333 |
Table 2
Date Unit NumColor
| 1/1/2021 | A1111 | Blue |
| 1/2/2021 | B2222 | Blue |
| 1/3/2021 | C3333 | Blue |
| 1/4/2021 | A1111 | Red |
| 1/5/2021 | B2222 | Yellow |
| 1/6/2021 | C3333 | Blue |
| 1/7/2021 | B2222 | Blue |
| 1/8/2021 | C3333 | Red |
Table 1 Result
Unit Num Color Value
| A1111 | 5 |
| B2222 | 0 |
| C3333 | 5 |
I am attempting to create a new column (Color Value on Table 1 Result) on Table 1 that Matches the Unit Num on Table 1 with the Unit on Table 2. It also needs to look up the MAX Date and if Num Color is Red return 5 if True and 0 if False.
I really appreciate you taking out time in your very busy lives to look into this for me. Thank You!

I created a column that returns the result you are looking for:Color Value = var __maxdate = MAXX( FILTER( 'Table 2', 'Table 2'[Unit] = 'Table 1'[Unit Num] ), 'Table 2'[Date] ) var __result = IF( ISEMPTY( FILTER( 'Table 2', 'Table 2'[Unit] = 'Table 1'[Unit Num] && 'Table 2'[Date] = __maxdate && 'Table 2'[NumColor] = "Red" ) ), 0, 5 ) return __result

Thank you.

Hi, MichaelBristol
Please check the below picture and the sample pbix file's link down below.
It is for creating a new column in Table1.
Color Value =
VAR currentunit = Table1[Unit Num]
VAR maxdatetable1 =
CALCULATE (
MAX ( Table2[Date] ),
FILTER ( Table2, Table2[Unit] = currentunit )
)
RETURN
IF (
CALCULATE (
SELECTEDVALUE ( Table2[NumColor] ),
FILTER ( Table2, Table2[Unit] = currentunit && Table2[Date] = maxdatetable1 )
) = "Red",
5,
0

While your solution looks like it should have worked, it created a Circular Dependency in my table. Thank you so much for looking into this!
