Next monday

[Reimer]

I would like a new calculated column date as follows: if today is monday, keep it. If not return the next monday. 

Ive tried this:

NextMonday = DATEADD(Dates[Date],MOD(7-WEEKDAY(Dates[Date],3),7),DAY) 

Power BI give no error, but the new column remains empty. What am I missing?

Doesit work for you:

MondayColumn =

var NextMonday= DatesTable[Date].[Date]-MOD(DatesTable[Date]-2,7)

return

if(WEEKDAY(DatesTable[Date],2)=1,DatesTable[Date],NextMonday)

[Reimer]

Well this is more then I can handle 🙂

Do I just copy this in my Power BI and change

"DatesTable for my column?

Is Invoerdatum your date column?

If yes, then remove the [Date] from everywhere where it is causing the error

[Reimer]

Thank you, no more Error. Just two small issues.

I am now using this formula:

But this is the output:

So, it return the previous Monday (and should return the next monday), and on Mondays (invoerdatum) it returns a very weird date (and should remain the same)

Can you help?

Ahh! my bad. 

yes you need to create a calculated column from ColumnTools --> New Column 

and paste this dax iformula there

And yes DatesTable is Dates[Date] for you

Something is still wrong?

@Reimer ,

This monday = 'Date'[Date]+-1*WEEKDAY('Date'[Date],2)+1

Next monday = 'Date'[Date]+-1*WEEKDAY('Date'[Date],2)+8

[Reimer]

Ive tried this, but is still not quite working. If I use:

Next monday = 'Date'[Date]+-1*WEEKDAY('Date'[Date],2)+8

Then all days of the week change in the next monday. But also the mondays change in the next monday. But mondays must remain the same.

So:

Monday 1 januari --> Monday 1 januari

Thuesday 2 januari --> Monday 8 januari

Wednessday 4 januari --> Monday 8 januari

Etc.

@Reimer , Try this if not resolved yet

Next monday = if(WEEKDAY([Date],2)=1, [Date],'Date'[Date]+ 8-1*WEEKDAY('Date'[Date],2) )

[Reimer]

WAUW, it is working.

Thank you all for your great help and patience!

Ive tried this as well. But the formula doesnt keep the monday:

Maandag publicatie = 'Procedures - Power BI'[Invoerdatum].[Date] - WEEKDAY('Procedures - Power BI'[Invoerdatum],2)+8
