Re: Not all items showing in Combo Box

Hi

I've a sharepoint list that has 20,000 records. What I'm trying to do is to enter the serial number in a combobox, and then do lookup to find the device description

Combobox items property:

'Metadata-MaterialList'.Material

The Default property for my InputText box:

LookUp('Metadata-MaterialList',Material=ComboBox1.Selected.Material,'Material Description')

Now the combo box is working fine and I'm getting results, but limited number of results. Some of the items I'm searching are not showing (though they exist in the sharepoint list).

I would appreciate any help.

@yjamous Combobox in no match for 20K records. As you may know, the maximum number of records PA will fetch from any datasource at one go it 2K. If you need all 20K values, you will have to fetch them in batches of 2K into collections and them combine them together into one big collection and use that for your search.

I believe this has something to do with the limitations of the SharePoint connection in PowerApps. It’s limited to a x amount of records. This could explain why not all records are showing up.

Can you please press on the stethoscope on the right top and see if there are any Delegation warnings? Those give the formula that doesn’t work with large amount of data.

I recently found a article (which I couldn’t find quickly) where someone imported the data in batches to a collection within the app and that collection did work with 10.000+ records.

I’ve you have any further questions please let me know.

kind regards.
