Advocate IHow to use if else with two conditions using DAX
Hi,
I am new to Power BI and I have data like this in sales table. I want to create a new column Max_price_new where 0 should be replaced by the Max_price of earlier quarter.
e.g. This is the input table
| article | yr&qua | quarter | Max_price | year |
| 10026858 | 2017Qtr 2 | Qtr 2 | 0 | 2017 |
| 10026858 | 2017Qtr 1 | Qtr 1 | 19537 | 2017 |
| 10026858 | 2016Qtr 3 | Qtr 3 | 19537 | 2016 |
| 10026858 | 2016Qtr 1 | Qtr 1 | 19537 | 2016 |
output table should look like:
| article | yr&qua | quarter | Max_prise | year | Max_Price_new |
| 10026858 | 2017Qtr 2 | Qtr 2 | 0 | 2017 | 19537 |
| 10026858 | 2017Qtr 1 | Qtr 1 | 19537 | 2017 | 19537 |
| 10026858 | 2016Qtr 3 | Qtr 3 | 19537 | 2016 | 19537 |
| 10026858 | 2016Qtr 1 | Qtr 1 | 19537 | 2016 | 19537 |
I have already written few formulas to find out:
1. Quarter number where the Max_Price is 0.
2. Find the earlier quarter number.
But I am struggling with how to find price of earlier quarter. i.e. in it should be something like
Max_Price_new = Max_Price where article= current article value and quarter = earlier quarter
How should I write this using DAX ?
Hi NewbeePowerBI,
Please refer to below calculated columns:
Quarter Num = RIGHT(Sheet1[quarter],1) Last quarter = IF ( Sheet1[Max_prise] = 0, CALCULATE ( MAX ( Sheet1[Quarter Num] ), FILTER ( ALLEXCEPT ( Sheet1, Sheet1[article], Sheet1[year] ), Sheet1[Quarter Num] < EARLIER ( Sheet1[Quarter Num] ) ) ), Sheet1[Quarter Num] ) Max_prise New = LOOKUPVALUE ( Sheet1[Max_prise], Sheet1[article], Sheet1[article], Sheet1[year], Sheet1[year], Sheet1[Quarter Num], Sheet1[Last quarter] )
Best regards,

You say you found a way to get the previous quarter. In my example I have a sequence number for the quarters with 1 starting at the earliest and 4 being the latest.
I also add 1 to each price, so you can see that you are getting the correct values.
You could create a statement like this to get the previous quarter value:
PreviousQuarterMaxPrice = VAR QuarterSequence =
MAX ( Sheet1[QuarterSequence] )
RETURN
CALCULATE (
MAX ( Sheet1[Max_price] ),
Sheet1[QuarterSequence]
= QuarterSequence - 1,
ALL ( Sheet1 )

NewbeePowerBIHi, Thank you for your solution.
Removing MAX from this MAX ( Sheet1[QuarterSequence] ) in your query gave me half the answer of my question.
But I also have many articles like this in the column "article". How to add article condition into query? I want each article's value to be displayede.g.
article yr&qua quarter Max_prise year Max_Price_new 10026858 2017Qtr 2 Qtr 2 0 2017 19537 10026858 2017Qtr 1 Qtr 1 19537 2017 19537 10026858 2016Qtr 3 Qtr 3 19537 2016 19537 10026858 2016Qtr 1 Qtr 1 19537 2016 19537 10026777 2016Qtr 2 Qtr 2 0 2016 10 10026777 2016Qtr 1 Qtr 1 10 2016
