If today's date is between Start Date and End Date, then output the week number in Week column



I have 2 lists in Sharepoint: IT Wellbeing Weeks which has the week number, as well as the dates of the respective week and Wellbeing Tracking List v2, which contains WeekNumber, WeekNumber:StartDate and WeekNumber:EndDate which are lookup columns from IT Wellbeing Weeks list.


Through powerapps, i would like to create a new column called "Current Week" (or use the existing Week column), whereby if today's date is between WeekNumber:StartDate and WeekNumber:EndDate, then display the respective week number in Current Week/Week. For example: Week 1 - StartDate = 1/27/2020, EndDate = 2/3/2020, if date today is the 28th (1/28/2020), then output "1" in Week. 


How can i achieve this?

You can use AddColumns() like this:


AddColumns(YourSPListName, "Current Week",And(StartDate <= Now(), EndDate >= Now()))


Here's the docs on AddColumns() for a better understanding of how it works.

Hi @EricLott ,


What if I were to insert the week number in an existing column i already have on SP i.e. Week?

Then you would use the Patch() function, giving it your data source, the row (or record) you want to update, then the column name and updated value.

Do you mean first to check which week is today in, then patch the corresponding weeknumber (lookup field) into Wellbeing Tracking List v2?

Are the WeekNumber:StartDate and WeekNumber:EndDate are additional columns from weeknumber?


Set(VarItem, LookUp('IT Wellbeing Weeks', 'Start Date'<= Now() && 'End Date'>= Now())); 
Patch('Wellbeing Tracking List v2', Defaults('Wellbeing Tracking List v2'), {Title: "Test", WeekNumber: 
Id: VarItem.ID
Value: VarItem.Week


Note: The formula is to create a new record, so I add a required "Title" column.

Note: To patch a lookup column, you have to patch a record containing '@odata.type', Id and Value.
