DAX Measure/Column Help

[arsene49]

Hi All, Need a help to create DAX measure/column.

There are 2 tables, below is the sample data
1.Year-Factor
which has Factor for each year

Year    Factor
2021    1.035
2022    1.035
2023    1.035
None   1

2.Fact
there will be muliple products, multiple years and price

Product Year Price
A        2020    10
B        2021    15
C        2022    20

Requirement -
there will be Year slicer in the page from Year-Factor table and user will be choosing the year

ex. when they select 2022
if we look at the fact table:
expected output -
for product A which belongs to year 2020
output= price * 2021factor * 2022factor (10*1.04*1.04)
for product B which belongs to year 2021
output= price * 2022factor

final measure output - sum of Product A output + Product B output + Product C output

ex. when they select 2023
expected output - 
for product A which belongs to year 2020
output= price * 2021factor * 2022factor * 2023factor(10*1.04*1.04*1.04)
for product B which belongs to year 2021
output= price * 2022factor *2023factor

final measure output - sum of Product A output + Product B output + Product C output

ex. when they select None, 
for Product A , measure output is just Price

expected output when each year selected:

			filter selection in slicer
Product	Year	Price	2021 selected	2022 selected	2023 selected	None Selected
A	2020	10	10.35	10.71225	11.08717875	10
B	2021	15	15	15.525	16.068375	15
C	2022	20	20	20	20.7	20

TotalCost=

VAR selected=SELECTEDVALUE(Year-Factor[Year])

VAR summed = SUMMARIZED('Fact',[Product],[Year],"PY")

VAR year='Year-Factor'[Year]  

      RETURN 

           'Fact'[Price]*(year+1,[Factor],"yf")*(yf+1,[Factor])

RETURN

    sumx(year,PY)

[lbendlin]

there will be Year slicer in the page from Year-Factor table and user will be choosing the year

For that to work the Year-Factor table must be disconnected.

Your expected output is unclear for products that fall outside the limits. Please indicate the expected outcome for all products and Year-Filter selections.

@lbendlin Thanks for the reply. i have added a table at the end of the question which shows the expected output when each value of the Year-Factor slicer is selected. let me know if you need any further information.

[arsene49]

@lbendlin i have added expected outcome for all products and Year-Filter selections. did you get chance to look?

[lbendlin]

Adjusted =
VAR yf =
    SELECTEDVALUE ( 'Year-Factor'[Year] )
VAR a =
    SUMMARIZE (
        'Fact',
        [Product],
        [Year],
        "sm",
            VAR y = [Year]
            RETURN
                SUM ( 'Fact'[Price] )
                    * IF (
                        yf = "None",
                        1,
                        COALESCE (
                            CALCULATE (
                                PRODUCTX ( 'Year-Factor', [Factor] ),
                                'Year-Factor'[Year] <= yf,
                                'Year-Factor'[Year] > y
                            ),
                            1
                        )
                    )
    )
RETURN
    SUMX ( a, [sm] )

Thanks @lbendlin 

just last help.

we have altred the Year-Factor table by adding an extra column "Factor2"

Year    Factor    Factor2
2021    1.035    0.98
2022    1.035    0.98
2023    1.035    0.98
None    1          1

now we need to consider Factor2 in the calculation when Year-Factor.Year < Fact.Year
for rest your given forumula is correct.

ex. for Product D - which belongs to year 2023
when they select 2021
expected output -
output= price * 2022 factor2 * 2023 factor2 (10*0.98*0.98)

when they select 2022
output= price * 2023 factor2 (10*0.98)

expected output. (you just need to add the scenario for the bold one in the current formula)

			filter selection in slicer
Product	Year	Price	2021 selected	2022 selected	2023 selected	None
A	2020	10	10.35	10.71225	11.08717875	10
B	2021	15	15	15.525	16.068375	15
C	2022	20	19.6	20	20.7	20
D	2023	10	9.604	9.8	10	10

[lbendlin]

You can change the PRODUCTX calculation accordingly. 

[arsene49]

@lbendlin tried playing around with that function, couldn't get the exact output. can you please help?

[lbendlin]

Have you replaced factor with factor2 in the formula?

it is not clear to me  what your expected outcome is. Please clearly indicate the expected outcome for all scenarios.

[arsene49]

Thanks for respoding @lbendlin . let me explain the scenarios - 

there are 3 scenarios based on the year filter selction we make and year in Fact where each product belongs.
1.Year Selected silcer (from Year-Factor) > Fact Table Year (for each product) = here we need to consider factor to multiply price
2.Year Selected (Year-Factor) < Fact Table Year = here we need to consider factor2 to multiply price
3.Year Selected (Year-Factor) = Fact Table Year and Year Selected (Year-Factor)="None" = here we need to consider 1 to multiply price

ex. when we select 2021 in the filter
if we look at the fact table:
expected output -
for product A which belongs to year 2020 (Here Year Selected silcer (from Year-Factor) > Fact Table Year (for each product))
output= price * 2021factor = (10*1.04)
for product B which belongs to year 2021 (Here Year Selected (Year-Factor) = Fact Table Year)
output= price * 1 = (15*1)
for product C which belongs to year 2022 (Here Year Selected (Year-Factor) < Fact Table Year)
output= price * 2021factor2 = (20*0.98)
for product D which belongs to year 2023 (Here Year Selected (Year-Factor) < Fact Table Year)
output= price * 2022factor2 *2021factor2= (10*0.98*0.98)

ex. when we select 2022 in the filter
if we look at the fact table:
expected output -
for product A which belongs to year 2020
output= price * 2021factor*2022factor = (10*1.04*1.04)
for product B which belongs to year 2021
output= price * 2021factor = (15*1.04)
for product C which belongs to year 2022
output= price * 1 = (20*1)
for product D which belongs to year 2023
output= price *2022factor2= (10*0.98)

final measure output = sum of Product A output + Product B output + Product C output + Product D output

Year-Factor table-

Year      Factor      Factor2
2021      1.035       0.98
2022      1.035       0.98
2023      1.035       0.98
None     1              1

expected output - 

			filter selection in slicer
Product	Year	Price	2021 selected	2022 selected	2023 selected	None
A	2020	10	10.35	10.71225	11.08717875	10
B	2021	15	15	15.525	16.068375	15
C	2022	20	19.6	20	20.7	20
D	2023	10	9.604	9.8	10	10
