Can't wait to watch the rest of the delegation videos! This is definitely going to help in the future when I start building sharepoint lists with a ton of data!
Thank you Reza for the great and useful video. I have spent a lot of time figuring out why my formula is throwing a delegation warning and by looking at your video I realized that ID column only delegates '=' operation. I wish I knew about your channel earlier. Subscribed in order not to miss new videos!
Thanks Reza, just a question: I have a list with more than 2000 records, and I have a label that I use to show number of total records filtered by some data: The code of the label is: Len( Concat( Filter( DataSourceRS; SystemUpdated = "YES" ); "X" ) ) I found that formula into a Powerapp forum!! To check, I have exported the sharepoint list in excel and I have applied the same filters in excel and the total records filtered was 2034 but the label contains 2000 as totale record counted. What's the correct formula should be used to count a lot of filtered records??
Excel data is stored locally in App so does not run into delegation issues but is not ideal for large data sources as all data is loaded into memory in App. Total count for delegable data sources would return max 2000 since CountRows is not a delegable function. I did a video showcasing a workaround for CountRows with SharePoint - ruclips.net/video/qsIn0mytC_8/видео.html
@@RezaDorrani I said that badly, my data source is Sharepoint, I have download sharepoint list into Excel to analyze data. I'll see your suggested video. Thanks a lot
Great video explaining delegation. One query though, if SharePoint has a limitation of 5000 rows/records, why does adding an index work? What is the index doing exactly?
Indexing ensures that you can query the list/library if the data in the list/library is greater than 5000 records. In SharePoint online (modern) - indexing is performed automatically as data grows. Note: You can only have a max of 20 indexes per SharePoint list/library. To know more about SharePoint limits - ruclips.net/video/AkyW8cWDVoc/видео.html
Great video and great Explanation. What if I use Excel Online as my data source, consists of more than 2000 records? As Excel Online is not a delegable data source, Is powerapps able to retrive the records more than 2000?
I prefer not to use excel for this reason. You would have to query and load data in batches and hold them in collections. Possible but has it challenges in terms of performance as well.
Thank you Reza, great video!.. quick question for you, how filter is not delegable for excel data source, do you have any idea how to handle it? I have to use excel in this case and not move to share point!! My big issue is filtering information using excel data source!! Best regards form Colombia man! 👍
Excel is not a delegable data source in Power Apps. You could load data into collections but will run into performance issues for large data sets. ♥ to Colombia
Reza, thank you for all the videos you create. They are extremely informative and very helpful. I recently ran into a delegation issue on a SQL table. I tried to resolve the issue by creating a clustered index to ensure that the newest records would appear first. But when I used this table in a Gallery, it doesn't use or display the data in the order of the clustered index. So my question is...when you create a data connection to a specific SQL table and use that table in the ITEM property of a Gallery, what is the default order of the data returned/displayed in the Gallery? Does it come back to the Gallery in order by a primary key? Is powerapp connections aware of clustered indexes?
Thanks so much! All great questions. The problem - I have done very little work with sql and power apps. Not sure how it handles or if it handles clustered indexes. You should be able to sort data from table based on your columns as long as that sort function column type is delegable. I will recommend checking on forums at powerusers.microsoft.com. I’m sure there are experts who have done work with SQL and Power Apps delegation.
@@RezaDorrani , thanks for the quick reply. I'll definitely check out the powerusers forum you provided a link to. I was able to resolve my issue by adding a SORT function to my filter statement. But I'm still curious to found out how and if powerapps uses SQL indexes. Thanks again.

Hello Reza, You have been wonderful all though this series of Delegation videos. One question though. I am trying to search based on Text Column and search text need not be the beginning Text of my Text Column Values. If my text value is "Power Automate", using StartsWith can only get results for "Power" query but not for "Automate" query. How can I bring the consistent search results for any text that I enter while handling the delegation issues.
StartsWith is a delegable function. I just tested with a space in the text example: "Power Automate" and it did return the results for me. I would recommend sharing screenshots of your issue with details on the Power Apps community forum - powerusers.microsoft.com/t5/General-Discussion/bd-p/PowerAppsForum1
How can we solve the problem in counting itens from a shrepoint list? The COUNT function is not delegable. We can not even use the SUM. How can we count a huge sharepoint list?
Hi Leonel, My latest delegation video shows the Count items workaround ruclips.net/video/yXvDj60-3YQ/видео.html My upcoming video will showcase SUM, Average etc.
Hi Reza. Thank you for all the excellent tutorials, they are awesome and really appreciated. I used the same SortByColumns and Starts StartsWith from your example, as soon as I type into the search box all content dissapears, even if I type in one letter. What could be the issue?
Thanks Reza, Just a little confusion, as per your example, if a student record is after 2,000 records, we can't use search on it ? instead we have to use filter and startswith ?

Yes. The workaround is not that neat though. I am currently working on a video for delegation workarounds.Blan Since or Not or ! is not delegable with SharePoint Text columns, you would have to frame your query in a different way. 1 example is as below: Filtering a sharepoint list called students where the Description column is not blank. So the query looks like below. It works as long as my text column starts with any of the alphabets. Can add numbers and other characters also in there. Filter(Students,StartsWith(Description,"a")||StartsWith(Description,"b")||StartsWith(Description,"c")||StartsWith(Description,"d")||StartsWith(Description,"e")||StartsWith(Description,"f")||StartsWith(Description,"g")||StartsWith(Description,"h")||StartsWith(Description,"i")||StartsWith(Description,"j")||StartsWith(Description,"k")||StartsWith(Description,"l")||StartsWith(Description,"m")||StartsWith(Description,"n")||StartsWith(Description,"o")||StartsWith(Description,"p")||StartsWith(Description,"q")||StartsWith(Description,"r")||StartsWith(Description,"s")||StartsWith(Description,"t")||StartsWith(Description,"u")||StartsWith(Description,"v")||StartsWith(Description,"w")||StartsWith(Description,"x")||StartsWith(Description,"y")||StartsWith(Description,"z"))
HI, Can we have a SharePoint list of 300,000 rows? or more than that and then looKup that list for further process in App??? like if I want to lookUp 289,899th row.. will it be performant and fast enough? to process when the Powerapp loads?
@@RezaDorrani I understand that but What I will do is connect that SP List in PowerApps and I will lookup in that SP on an indexed column as you said using filter and Lookup will it work ? And find that 289,899th record?
@@mustafahussainmohsin320 Yes as long as that query is delegable - it will search entire data set but only return data in batches. Plz watch entire delegation playlist to understand how delegation truly works. No user will put a query to say get me 289899th record. The query would be more on lines of get items with status X, due date today, priority Y etc.
Why do you need 6000 items in a collection? That is not best practice. Just query data source and ensure you are not getting a delegation warning. Power Apps can work with millions of records if delegation is in check. Loding data in collections will load data on the users device. Imagine that much info on a mobile App.
@@RezaDorrani I am planning a dashboard of Migration summary. My query mostly includes Filter and CountRows. If I am using List directly I am getting delegation warnings. My filter query is on Choice, single line of text columns and then get count of those items. I have seen in ur video coutrows is not a delegable function and we should go for flows. But how far using flows in my scenario is efficient I have to check.
Nice video but I have one doubt... Do gallery by default will load 20k items in chunk of 100 ( do we need to scroll , to get next 100 items, till we reach 20k th item)??
Yes, but give me 1 user in the world who would do that :) It is important therefore to define good filters so that users can refine the results. Check - ruclips.net/video/5dSk5iOgT68/видео.html

Depends how you are stoing those links and what type of column it is. There are certain bugs in Power Apps related to links. powerusers.microsoft.com/t5/Building-Power-Apps/Links-to-SharePoint-from-PowerApp-not-working/td-p/412439
Also how could you search beyond the limit of 50 records when the count is fixed at 50. I have using same expression in the gallery items property like starts with
If query is delegable it will perform the operation on large data sets. Im not sure what you are trying though. Il recommend posting your query with screenshots on the forums at powerusers.microsoft.com
Thanks for the quick response Reza. I have a gallery connected to Share point list which has around 450 rows for now. But it can grow in future suppose beyond 2k records.

Filter(Students,StartsWith(Description,"a")||StartsWith(Description,"b")||StartsWith(Description,"c")||StartsWith(Description,"d")||StartsWith(Description,"e")||StartsWith(Description,"f")||StartsWith(Description,"g")||StartsWith(Description,"h")||StartsWith(Description,"i")||StartsWith(Description,"j")||StartsWith(Description,"k")||StartsWith(Description,"l")||StartsWith(Description,"m")||StartsWith(Description,"n")||StartsWith(Description,"o")||StartsWith(Description,"p")||StartsWith(Description,"q")||StartsWith(Description,"r")||StartsWith(Description,"s")||StartsWith(Description,"t")||StartsWith(Description,"u")||StartsWith(Description,"v")||StartsWith(Description,"w")||StartsWith(Description,"x")||StartsWith(Description,"y")||StartsWith(Description,"z"))
Hello, check if your case is covered here ruclips.net/video/yXvDj60-3YQ/видео.html
HI, Can we have a SharePoint list of 300,000 rows? or more than that and then looKup that list for further process in App??? like if I want to lookUp 289,899th row.. will it be performant and fast enough? to process when the Powerapp loads?
As long as delegation is handled, Power Apps can work with large data
@@RezaDorrani but is it necessary to load all the data into PowerApps? In order to LookUp?? From it?
@@mustafahussainmohsin320 Whole idea of delegation is bringing data in batches.
@@RezaDorrani I understand that but What I will do is connect that SP List in PowerApps and I will lookup in that SP on an indexed column as you said using filter and Lookup will it work ? And find that 289,899th record?
@@mustafahussainmohsin320 Yes as long as that
query is delegable - it will search entire data set but only return data in batches. Plz watch entire delegation playlist to understand how delegation truly works.
No user will put a query to say get me 289899th record. The query would be more on lines of get items with status X, due date today, priority Y etc.
Reza can u explain me how to collect 6000items of a sp list into powerapps clearcollect.
Why do you need 6000 items in a collection?
That is not best practice. Just query data source and ensure you are not getting a delegation warning. Power Apps can work with millions of records if delegation is in check.
Loding data in collections will load data on the users device. Imagine that much info on a mobile App.
@@RezaDorrani I am planning a dashboard of Migration summary. My query mostly includes Filter and CountRows. If I am using List directly I am getting delegation warnings. My filter query is on Choice, single line of text columns and then get count of those items. I have seen in ur video coutrows is not a delegable function and we should go for flows. But how far using flows in my scenario is efficient I have to check.
@@saiabhinav3554 You will have to use flows. What if your list keeps growing. You can’t just keep loading data.
Nice video but I have one doubt...
Do gallery by default will load 20k items in chunk of 100 ( do we need to scroll , to get next 100 items, till we reach 20k th item)??
Yes, but give me 1 user in the world who would do that :)
It is important therefore to define good filters so that users can refine the results.
Check - ruclips.net/video/5dSk5iOgT68/видео.html
@@RezaDorrani yes definately no one will do that, just doubt so asked.
One more doubt, in filter 20kTh record will be shown after we enter text in seach box?
Is this my understanding right?
@@raj7sam Search is not delegable with SharePoint as a data source. Check my playlist on delegation.
I am using Filter(list, created > Date(2000,1,1)). It is delegable function but not getting expected results
I only get 500 records but I should be getting 4000 records
how are you checking the 500 number?
Hi Reza
Could you please help me with this
I have saved video links in Sharepoint list , connecting sharepoint to power apps, i wanted to play the videos in Power apps, i'm able to play itin power app browser but not in mobile device it is showing black screen
Depends how you are stoing those links and what type of column it is. There are certain bugs in Power Apps related to links.

Welcome!
I am facing delegation warning, though I have increased the row count from 500 to 2000 but still I have the warning. I have around 450 records
Also how could you search beyond the limit of 50 records when the count is fixed at 50. I have using same expression in the gallery items property like starts with
Delegation warning will not go away is formula is not delegable. Changing limit from 500 to 2000 will only tell power apps to fetch more rows.
If query is delegable it will perform the operation on large data sets. Im not sure what you are trying though. Il recommend posting your query with screenshots on the forums at powerusers.microsoft.com
Thanks for the quick response Reza. I have a gallery connected to Share point list which has around 450 rows for now. But it can grow in future suppose beyond 2k records.
I want to have a text input box as a search input for name of person from the data available in SharePoint list. Just want to make sure even if records exceed the 2000 mark , my search input box should work. Currently it is working fine using sort and filter functions just as the example in the video.
@@ahujakran As long as there is no delegation warning, you will be fine

SortByColumns(Filter([@DSVT]; StartsWith(MVT; TextSearchBox1.Text)|| StartsWith(CHITIET; TextSearchBox1.Text)) ; "ID"; If(SortDescending1; SortOrder.Descending; SortOrder.Ascending)) . I have more than 2000 lines of data, how can I search the text in the dark search for the following characters, for example: Name: John Wiliams, I filter the word "Wiliams" and still search Okay.
