I will show you how to use variables to avoid delegation issues when filtering a date range. In this example, we will filter a table to show only dates within the next ‘N’ number of months where N is a number specified by the app maker.
Input
Calendar Dates is a SharePoint list with consecutive days starting 1/1/2018 and ending 12/31/2024 (2,557 rows)
| Title | CalendarDate |
| Monday, January 1, 2018 | 1/1/2018 |
| Tuesday, January 2, 2018 | 1/2/2018 |
| Wednesday, January 3, 2018 | 1/3/2018 |
| Thursday, January 4, 2018 | 1/4/2018 |
| Friday, January 5, 2018 | 1/5/2018 |
| … | … |
| Tuesday, December 31, 2024 | 12/31/2024 |
Original Code
The WITH function only partially supports delegation. This means the number or results cannot exceed the non-delegation record limit (500 rows by default, 2000 maximum).
With(
{
StartDate: Date(
Year(Today()),
Month(Today()),
Day(Today())
),
EndDate: Date(
Year(Today()),
Month(Today())+2, //change this number
Day(Today())
)-1
},
Filter(
'Calendar Dates',
CalendarDate >= StartDate,
CalendarDate <= EndDate
)
)
Delegation-Friendly Code
Set the StartDate and EndDate variables prior to using them inside a filter function.
Set(
StartDate,
Date(
Year(Today()),
Month(Today()),
Day(Today())
)
);
Set(
EndDate,
Date(
Year(Today()),
Month(Today())+2, //change this number
Day(Today())
)-1
)
Use this improved code in the Items property of a gallery.
Filter(
'Calendar Dates',
CalendarDate >= StartDate,
CalendarDate <= EndDate
)
Output
Shows only rows with a date in the next 2 months. Current date is 6/16/2021
