Question

I have two tables:
Table 1
Year Name Score
2010 A 1000
2011 A 1200
2012 A 1200
2013 A 1300
2010 B 1100
2011 B 1500
2012 B 1300
2013 B 1600
Table 2
Year Factor
2010 3.57
2011 4.21
2012 6.11
2013 2.15
I would like to do this: match two tables, as long as Year in Table 1 match Year in Table 2, divide the score by the factor, e.g. for A in 2010, 1000/3.57; for B in 2010,1100/3.57
How to revise the following code?
adjusted score =
VAR
filter (all('Table 1'[Year]), 'Table 1'[Year]='Table 2'[Year])
RETURN
DIVIDE ('Table 1' [Score], 'Table 2'[Factor')
Thank you very much!

Answer 1

If you are looking for a measure, you can try this below code-
adjusted score =
VAR current_row_year = MIN('Table 1'[Year])
VAR current_row_Score = MIN('Table 1'[Score])
VAR factor =
CALCULATE(
MAX('Table 2'[Factor'),
filter (
all('Table 2'),
'Table 2'[Year]= current_row_year
)
)
RETURN DIVIDE (current_row_Score, factor)
Code for a Custom Column is as below-
adjusted score =
VAR current_row_year = 'Table 1'[Year]
VAR current_row_Score = 'Table 1'[Score]
VAR factor =
CALCULATE(
MAX('Table 2'[Factor'),
filter (
all('Table 2'),
'Table 2'[Year]= current_row_year
)
)
RETURN DIVIDE (current_row_Score, factor)
You can also do the same using Transformation using Power query. In that case you have to just merge your table 1 and 2 using Year and then after Expanding the table, you will have Factor in each row for the Year. You can then just add a new custom column with - Score/Factor
