Comparing two columns and set colors for specific match in Power BI

[creyssonbr]

Hi,

I want to retrieve a value from two common rows and use if to return color, for conditional formatting in Power BI, as the following requirement:

1. If content doesn't show on table 1 and doesn't show on table 2, set black.
2. If content shows on table 1 and not on table 2 and age1 is less than 10, set yellow.
3. If content shows on table 1 and not on table 2 and age1 is equal to 10, set purple.
4. If content shows on table 1 and not on table 2 and age1 is more than 10, set red.
5. If content shows on table 1 and on table 2, set green.

Content is text. Age is whole number.

I tried the following measure, but something is wrong with IF statement. I'm not sure if the SELECTEDVALUE is the right funtion to use here. I'm open to any suggestion and thanks a lot for your help.

Content Check = 
VAR C1= SELECTEDVALUE (Table1[Content]) 
VAR C2= SELECTEDVALUE (Table2[Content]) 
VAR Age SELECTEDVALUE (Table1[Age]) 
VAR Color= "#000000" #Black by default
IF (Invoice <> Journal, 
    Color="00FF00", 
    IF (Age > 10, 
        Color "#FF0000", 
        IF (Age <10, 
            Color="#FFFF00", 
            Color="#FF00FF"))) 

RETURN Color

Table1

|      Content        |     Age    |
|---------------------|------------|
|          Bravo      |         1  |
|          Alpha      |         5  | 
|          Charlie    |         10 |
|          Tango      |         3  |
|          Delta      |         22 |
|          Golf       |         42 |

Table2

|      Content        |  
|---------------------|
|          Alpha      |
|          Charlie    | 
|          Delta      | 
|          Golf       |  

The point here is to scan every row in table one and determine if it's there in table 2 too. If not, will return RGB Black. If it's there, it will be comparing Table1 Age, to check what color should be set.

Worked like a charm!

Thank you so much for this perfect and detailed solution Harsh.

HI @creyssonbr ,

Create a Calculated Column in Table A

ContentTableB = LOOKUPVALUE(TableB[Content],TableB[Content],TableA[Content])

You can use this measure

Measure = SWITCH
(
    TRUE(),
     MAX(TableA[ContentTableB]) = BLANK() && MAX(TableA[Age]) < 10,"Yellow",
     MAX(TableA[ContentTableB]) = BLANK() && MAX(TableA[Age]) = 10,"Purple",
     MAX(TableA[ContentTableB]) = BLANK() && MAX(TableA[Age]) = 10,"Red",
     MAX(TableA[ContentTableB]) = MAX(TableA[Content]),"Green",
     "Black"
     )

Follow the stps:
