Filter table, convert column from integer to date and +1 day
Hi,
What I'm trying to do is:
1st step: filter table, this works with the DAX:
Hi , Thank you for reaching out to the Microsoft Community Forum.
I have reproduced your scenario in Power BI Desktop and successfully implemented a solution where we built a DAX measure that counts distinct contracts from the FEIT_Verhuur table where WAARDEGETAL = 1.00 and Subonderwerp = "Days", and shifts the DateInt value forward by one day to get NextDay. A disconnected MonthTable slicer allows users to filter based on the month of this NextDay. The measure updates visuals like a card to show how many contracts roll over into the selected month, such as showing February results when DateInt is 20250131.
For your reference, I’ve attached the working .pbix file.

Thank you.Hi Youri98
Yes, what you're trying to do in Power BI is definitely possible using DAX, and it can be broken down into three clear steps. In the first step, you've already correctly filtered your data using a CALCULATE expression to count distinct contract keys based on conditions like WAARDEGETAL = 1.00 and specific Subonderwerp values. In the second step, since your date is stored as an integer in the format YYYYMMDD (e.g., 20250131), you can convert it to a proper date using the DATE() function in DAX. This involves extracting the year, month, and day using basic arithmetic. For example, you can create a calculated column with:
ConvertedDate = DATE( DIVIDE('FEIT_Verhuur'[DateInt], 10000), MOD(DIVIDE('FEIT_Verhuur'[DateInt], 100), 100), MOD('FEIT_Verhuur'[DateInt], 100) )This will transform an integer like 20250131 into a true date value. In the third step, you can then add 1 day to this new date using +1, like this:
ShiftedDate = 'FEIT_Verhuur'[ConvertedDate] + 1This effectively moves end-of-month dates (e.g., January 31) into the next month (e.g., February 1), which is useful when you want to report activities as occurring in the following month. So yes, by using DAX in calculated columns, you can convert the integer to a date and shift it forward by one day for your reporting logic.

Hi Youri98,
Thank you for reaching out to Microsoft Fabric Community Forum.
After multiple workarounds, I found that the IntegerDate column should be in text format. If it's stored as a whole number, Power BI misinterprets the data type, leading to incorrect results.
Create a new Calculated column for converting IntegerDate to a date:
ConvertedDate = VAR DateText = FORMAT(Sheet1[IntegerDate], "00000000") -- Ensures 8-digit format RETURN DATE( LEFT(DateText, 4), -- Extract Year MID(DateText, 5, 2), -- Extract Month RIGHT(DateText, 2) -- Extract Day )Create another new column to add +1 day:
NextDay = Sheet1[ConvertedDate].[Date] + 1Here is the output in DD/MM/YYYY format:

Regards,
Vinay PabbuThank you for the reply. As we don't manage the data set I can't add columns myself so that's why I wanted to see if it would be possible with DAX. But I got multiple messages now saying that it's not possible with DAX. Thanks for trying to help. I guess I'll just have to get back to the owners of the data set and see if they can add the columns for me.
Hi Youri98,
Thanks for the update. I hope that solves your issue. Please share the details here after it is solved.

You can use the DATE function to convert the integer date to a date type. Assuming your integer date is in the format YYYYMMDD, you can use the following DAX formula:
dax
ConvertedDate =
DATE(
INT(LEFT(FEIT_Verhuur[IntegerDate], 4)),
INT(MID(FEIT_Verhuur[IntegerDate], 5, 2)),
INT(RIGHT(FEIT_Verhuur[IntegerDate], 2))
)Once you have the date in the correct format, you can add one day to it using the DATEADD function:
dax
NextMonthDate =
DATEADD(
DATE(
INT(LEFT(FEIT_Verhuur[IntegerDate], 4)),
INT(MID(FEIT_Verhuur[IntegerDate], 5, 2)),
INT(RIGHT(FEIT_Verhuur[IntegerDate], 2))
),
1,
DAY
)So, I can do both in 1 DAX directly, right? And how would I use this date in combination with the filters I used in the different DAX.
Youri98 You can combine using var
dax
Aantal aansluitend verhuurd =
CALCULATE(
DISTINCTCOUNT('FEIT_Verhuur'[%ContractKey]),
FEIT_Verhuur[WAARDEGETAL] = 1.00,
FEIT_Verhuur[Subonderwerp] IN { "Days" },
VAR ConvertedDate = DATE(
INT(LEFT(FEIT_Verhuur[IntegerDate], 4)),
INT(MID(FEIT_Verhuur[IntegerDate], 5, 2)),
INT(RIGHT(FEIT_Verhuur[IntegerDate], 2))
)
RETURN DATEADD(ConvertedDate, 1, DAY)
)
Well, you could convert the number to a string (FORMAT) and then to a date (DATEVALUE), but I do not recommend doing this in DAX at all. You're better of doing this sort of thing in Power Query, or even your data source.
Thanks for the reply, if this was an option I would do it as well. But this is not possible in this situation.
