Remove items in sharepoint library that does not match

Hello everyone,

I'm trying to expand an app, where I've come across a challenge.

I have a button that creates a new item in a sharepoint library, based on week numbers, and I only want the newest week to appear in the library for other use in the app.
But I dont know how to write the code I need for it to look up in the sharepoint library, and remove other elements that does not have the week number I just wrote.

I'm looking for something like

If(
 Lookup(
 Sharepoint library; Title != Textinput.Text);
#Where I want it to delete the items that does not equal the week number, and not do anything if it is the same

But I dont know how to write the code.

Any help is much appreciated!

Hi @MortenBak ,

If you want to remove items in the library based on conditions, you can try using the formula RemoveIf().

My library:

Add a Button to the app and set the ‘OnSelect’ to the following formula:

RemoveIf(Test11,Not(WeekNum(Created)=WeekNum(Today())) Or Not(Year(Created)=Year(Today())))

After clicking, It removed files that are not this week.

Best Regards,

Wearsky

Hello Wearsky,

I played with some other ways of doing it, and ended up using Last(Sharepointlist), and then creating a flow to delete files thats older than a month. I'm sure this would have done the trick as well, and I'll probably add this the next time I'm playing with PowerApps.

Thank you for the response!
