Using a calculated date column from SharePoint in a formula on Power Apps to show items expiring soon

(0) ShareShare
ReportReport
Posted on by Laela 21

Hi there, 

 

I have created a Calculated column on SharePoint List to calculate an Expiry Date for 4 years after a date which the user inputs. In the calculated column, I've used the following formula:

=DATE(YEAR([User Input Date])+4,MONTH([User Input Date]),DAY([User Input Date]))

 

Then, on Power Apps, I am attempting to show items that are expiring in the next 6 months by filtering the Expiry Date in a Gallery with the following formula:

Filter('Date source', 'Expiry Date' <= DateAdd( Today(), 180 ),!IsBlank('Expiry (Date'))

 

I am getting an error in the formula that says "Invalid argument type. Expecting a number value". 

The date is returning as a string and is returning in this format as an example:

yyyy-mm-ddT08:00:00Z

 

Please help me understand how to get the date in the correct format so that I can use it in a Power Apps formula (i.e. the Gallery formula described above).

    Hi @Laela ,

    Happy to a explore a solution if you need to use your methodology, but I will make a suggestion first. If the source fields of the calculated column are available in PowerApps, why not do the lookups there?

    Hi @WarrenBelz 

     

    Thank you for your reply. Please elaborate on what you meant by if the source fields are available in Power Apps?

     

    Just to give more context:

    • I have a Power Apps Edit Form on a screen where a user will input a date. An expiry date needs to be automatically calculated from that to be 4 years away from the user input date, and saved in my SharePoint List as an "Expiry Date". 
    • I have a gallery on a separate screen where "Expiry Date" data will be filtered to only show "Expiry Dates" that are 6 months away or less. The formula for this is not working though. 

     

    Regards,

    Laela

    Thanks @Laela ,

    I am referring to the fact SharePoint Calculated Columns are based on other fields in the data set which PowerApps also has vision of so the calculation

    DATE(YEAR([User Input Date])+4,MONTH([User Input Date]),DAY([User Input Date]))

    could easily be done in Power Apps as 'User Input Date' is available so

    DateValue(
 Month(DateValue('User Input Date'.Text))
 & "/" & 
 Day(DateValue('User Input Date'.Text)) 
 & "/" & 
 Year(DateValue('User Input Date'.Text)) +4
)

    will get the calculated field value you did in SharePoint

    Hi @WarrenBelz 

     

    Thank you for your suggestion. 

     

    I managed to figure out a way to do it with the SharePoint calculated column though. 

    I did it this way just in case a user decides to update the User Input Date from the SharePoint List, because they will have access to edit the SharePoint List as well. 

     

    My Solution is:

     

    In my SharePoint List calculated column, I had the following formula to make the expiry date 4 years ahead of the User Input Date (I added the ISBLANK in case a user does not input a date):

    =IF(ISBLANK([User Input Date]),"",DATE(YEAR([User Input Date)])+4,MONTH([User Input Date]),DAY([User Input Date])))

     

    In my PowerApps Gallery, I have the formula to flag dates that are 6 months away from the expiry date:

    Filter('Data source', DateValue('Expiry Date') <= DateAdd( Today(), 180 )&&DateValue('Expiry Date',"en-GB") >= DateAdd( Today(), -180 ),!IsBlank('Expiry Date'))

    For anyone who is not familiar with it, here is the link to the DateValue page: https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/functions/function-datevalue-timevalue

    "Converts a date, a time, or both in a string to a date/time value."

     

    Then, if I want to display the date in a label, I have the formula:

    Text(DateValue(ThisItem.'Expiry Date'),ShortDate)

     

    Regards,

    Hi @Laela ,

    A little curious -  you do not need to delete the SharePoint column to do the direct PowerApps lookup - you just don't use it in PowerApps, however I am glad it worked for you.

    Hello!  I'm looking to do the same but for these date parameters 30,60,90,120,730 and 1095 days to expire, I have tried several formulas, but it doesn't work, if you can help me on this, I will really appreciate it. I've been trying to use these formulas: =[TODAY]()-[Expiration Date], =IF([Expiration Date]-120 <= NOW(),"Expired","Not Expired")
    =IF([Expiration Date]-[Today]>90;"Expired","Not Expired")

    Hi @lcdelgado ,

    Try this

    With(
 {
 wDate:
 DateAdd(
 Today(),
 -120,
 Days
 )
 },
 If(
 'Expiration Date' <= wDate,
 "Expired",
 "Not Expired"
 )
)

    Thank you, Warren! it really helps me a lot! I have another question and it's about the concat formula! I have this formula for 30 days: 

     

    concat(concat('ExpirationDate',' ge ', '''',outputs('Today_+_x_days')),'''',' and ', concat('ExpirationDate',' lt ','''', outputs('x_Days_+_30'),'''')) 

     

    but when I tried to include 60 days it is giving me an error (Bad Request), this is the 60 days formula: 

     

    concat(concat(concat('ExpirationDate',' ge ', '''',outputs('Today_+_x_days')),'''',' and ', concat('ExpirationDate',' lt ','''', outputs('x_Days_+_30'),'''', 'ExpirationDate',' ge ', '''',outputs('Today_+_x_days')),'''',' and ', concat('ExpirationDate',' lt ','''', outputs('x_Days_+_60'),'''')))

    Can you try to help me here? thanks in advance
