Delegation I do not understand.

[yanni99]

I have a delegation warning with a Sharepoint list I cannot get my head around and fix. 

Filter(SharepointList, Column in PowerappsCollection)

I get the blue wavy thing under the "in". I cannot figure out how I can do differently. The SharepointList might have 10 000+ items and PowerappsCollection only up to 100 and is only one column. 

Can you help me figure this out?

In operator is  not delegable with SharePoint

What is your use case?

The In operator is not delegable to data sources.  This is definitely why you are getting that warning.

If your datasource is over the record limit, then you can consider another option IF your data column meets the delegable criteria.

    ForAll(PowerAppsCollection, Lookup(SharePointList, delegableColumn = Value))

This will return a table of all the items in the SharePoint list that match the criteria.  (please note, the ForAll function returns a Table...you can use it - on Items properties, collections, variables, etc)

The above assumes a single column collection.  If your PowerAppsCollection has more columns in it, then replace the "Value" above with the column from your collection that you want to compare against a delegable column in SharePoint.

NOTE: if you stick to = (equal) operators on SharePoint, most things will be delegable except datatime columns.  Please refer to the SharePoint connector docs for more on delegable options.

I hope this is clear and helpful for you.
