Moving collections to NamedFormulas really boosts!! 🚀🚀 Having a complex app with 15 screens >30 datasources and >20 collections, where I moved majority of collections (only static) to Formulas now. Result is impressiv: App loading time went down from 3-5 sec to 1 sec. !! Thx again for sharing this !
It goes without saying that anyone who watches Reza's tutorial is taken from basic to advanced skills. The way he has laveraged the user defined function to complex calculation was insane. Great tutorial, Reza!1
Very well explained, Reza! The way you breakdown each topic with use cases is just amazing. It clears up all my doubts, and I dont need to search around anymore. Thank you so much for making learning powerapps so easy and enjoyable..!!
I had already incorporated named formulas when it was first introduced, but at the time, collections were not yet permitted. Thank you so much sharing this and I will now update the rest!!!
Reza - great video as always. Very informative tutorial regarding this game-changing feature and thanks for the pragmatic advice regarding performance. Named Formulas and UDFs do not suffer a penalty hit, while variables do, very eye-opening. OnLoad code definitely belongs in these the App > Formulas. Thanks so much for producing and sharing!
Fantastic Reza! I have an exact use case for this and you have just provided me with the solution! Thank you for another excellent video showcasing the functions. ✨🚀
UDF are a great enhancement, but they come with a small downside: To auto-format your code in “Formulas”, you’ll need to remove it first or comment-out /* */ . The other thing on named formulas, especially when replacing collections, they are not listed under Variables (X), so that there is a bit the overview lost… Certainly by marking it you’ll see the table/content. So good would to have another grouping to list down the NamedFormulas below Collections. Thanks Reza, for sharing this in such a great explanatory way, you are my first choice of information the Apps & Flows.
Awesome work. Are the UDFs usable in a gallery so the values of a particular item are used in a formula to calculate and display a result in the gallery via a label? So the parameters passed to the UDF can therefore something like ThisItem.ColumnA or ThisItem.ColumnB.Value?
Certainly able to handle some more complexity, only missing the ability to handle some behavioural functions which I am having to repeat on a number of controls. Otherwise has cleaned up a lot of duplication.
OMG! This is pure gold!!! Thank you for sharing Reza.... quick question, if I use a Named Formula in a gallery, I will not be able to do the grid approach you explained in one of your videos where you can add (patch) records to the gallery and then to the datasource, will that be a limitaton of namedformulas?
Great video reza, thanks for sharing ;) Using those formulas instead of onstart seems to be really efficient!

Thanks for this video. I had considered the formulas as constants until now. I didn't know they were updated based on arguments. Do the delegation criteria apply in this case?
Great video Reza! Quick question, when using name formulas to filter a table do you know if it adds any delegation to it? e.g. a collection can only hold so many records but this isn’t creating a local copy so does it have that limit?
@@RezaDorrani I am finding the opposite. I have a large Filter() setup. When I put in App.Formulas I'm limited to 500. I put back into Gallery.Items and it's fine. Suggestions?
Hi Reza, you are right. This is a game-changer. I do have one question though. If I create a collection named formula, as you mentioned, it will be executed only when needed. Then, what if I am referring to the collection multiple times and on multiple screens? Does it make it an expensive operation?
It will run the formula when needed on demand as you land on those screens. It does do smart caching as well. Easiest way to check if to run monitor tool and see the api calls.
Thanks for your video and so informative. I assume all these named formulas will load when the app starts run and if the value is never used, then those formula need never be calculated.
Thanks for the amazing video! I got below questions. It will be really helpful for me if you provide some insights on these. Thanks in advance. Are named formulas delegable? Gallery loads records in batches of 100 for performance optimization. If we use named formula in such case, will my gallery show all records? Will data row limit affect named formulas?
Delegable as long as query is delegable. Gallery will load data in batches of 100 with named formulas (as long as query is delegable against data source)
absolutely brilliant Rezza, I've been meaining to learn this to move most, if not all my App.OnStart variables to named formulas. One thing I have been trying to do is use a sharepoint list of roles, so I can control who can view different views in my Apps e.g. Security role and use this to control and filter galleries. I know you did one a couple of years ago but unable to find it. And my question is can this be done using Named Formulas?
Thanks so much! Absolutely, named formulas is the way to go. Here is the video you are looking out for ruclips.net/video/dIzOAbMjN7g/видео.htmlsi=xKqPYLJXnUnEUqDn
Just one question, i have a list of 8 items in the Security list for business area, can i filter against the list in the named formula for each business area so that a logged in user can only see what he has item level permissions for?
Great vid! :) Was wondering - In order to use User Defined Functions you need activate new analysis engine, I've seen that people have reported several errors after activating it, have you experienced any issues regarding this?
Does Named Formulas or User Defined Function support Patch() ?? I want to create a Custom Function to Patch some data as i use the same Patch function in several screens.
Hi Reza, amazing video once again! Is there a way to use User Defined Functions in behavior like OnSelect. To make a Patch to Dataverse Generic from different places in the app for instance?
Great video. I am very confused with where you changed the collection colItems to a named formula nfHighPriorityTasks. The nfHighPriorityTasks table is not visible in the variables section like collections are. Is it stored locally somewhere?
Hi Reza, Does UDF support using a custom connector inside the UDF? Do you have any articles or code samples for this? Is return type in UDF compulsory since the custom connector just writes to SQL. Any help would be appreciated 🙂
Hi rezza, ive just added named formulas but how do you control the splash screen when its visibility is dependent on the data from a collection in named formula? In OnStart, you can just add set variables of the loading screen before and after the collection.
Thank you as always! Question, doesn't this way make many more calls to the database compared to collections? Example, I have a collection of employees. In many galleries with records inserted by employees I want their picture to be displayed. With a collection I made one single call OnStart, wouldn't NamedFormulas make 1 call for each record of the galleries to retrieve the pictures of employees having hundreds of separate calls each time? Also, would views from Sql Server also be automatically refreshed?
Hi Reza, Thank you for sharing this. When multiple users are simultaneously working on the same app, if User 1 updates an item, will that update automatically reflect for User 2 without requiring a manual refresh?
It wont update automatically. Its the same behavior for any other feature in Power App. A manual refresh or restart of app or execution of a delegable function via an action like go to screen or button click would be needed.
Thank you, Reza, for the access. Will this named formulas work in ForAll loop? if there is no sequence in named formula, that means we cannot use dependent formula?
Great video, thank you Reza! Waiting from Microsoft for the day when we can define full functions with multiple lines of code, Patch functionality and any kind of Parameter or Return types 🙏🏼
Great video, thank you very much! There are some cases when I need to use a collection within a single screen (when modifying a gallery and patching the result to DB, for instance). Can such collection be "local" to save pc memory?
Named formulas, collections and variables each have their use cases. None of them should be used as a data source. Check savedata loaddata functions for your scenario
Thanks, Reza. I have a need to do a block of code from multiple spots in my app, e.g., clear a block of variables. Could we do a parameter-less Custom Formula that can execute several statements at once, allowing me to just call the function wherever I need to execute the statements? Something like: nfClearSignatureVars():Boolean = Set(varSignBlob, Blank()); Set(varSignBinary, Blank()); Set(varSignPrintedName, Blank());

Hi Reza, question about the named formulas and having your datasource filtering there instead of inside the gallery itself... are there any delegation concerns? or is the named formula acting like it was written inside the gallery's "items" property?
Hi Reza, I have some complex collections I use that I've split into two collections: 1 to collect the raw data and another to do non-delegable functions on the raw data. How does this play into Formulas? Just now when I tried transferring these collections over to formulas and added the named formula to a gallery, it almost stalled out the app. 😅 Any pointers? Should I get the raw data as a formula and a normal collection for the complex work afterwards? Or the other way around?
@@RezaDorrani Thank you! So if I need to perform functions that are not delegable, like "AddColumns", should I use the Named Formulas to get the raw data first, such as just filtering by RecordStatus = "Active", and then create a collection off of that Named Formula? I guess I'm just trying to determine whether it is faster this way or if I should just do it all using collections instead. Appreciate the response if you have the time. Thank you again!
Hi @Reza. This video really helped during my first POC. I ran into an issue. not sure if its a bug.

I tried removing the data source and adding it again but didnt help. Request your assistance please. Thanks again
Hi Reza! This is great. I can´t activate named formulas in my Power Apps tho. I can see the Formulas property in the App screen but it doesn't work and I am sure I am using the right syntax.

In a sense, does this not dramatically minimize the use of collections? Almost to the point that named formula's would replace collections, except for discrete use cases?
I have defined a named formula : gblColorBlue = RGBA(0,179,228,1); but when I pass gblColorBlue to a component as input properties. It retunes error: Name isn't valid.

but when I pass gblColorBlue to a component as input properties. It retunes error: Name isn't valid. 'gblColorBlue ' isn't recognized.
I workaround it by define a variable at App.OnStart:
varColorBlue = gblColorBlue
then pass varColorBlue to component.
Is it the suggested workaround?
I have not used components in a long time and hence not sure of the workarounds.
I will recommend posting your query on the forums at powerusers.microsoft.com in case someone has done something similar.
That's really cool respect from Pakistan
Thanks
Hello Reza, Is there any way i can remove the attachment from the sharepoint list through Powerapps? for other fields we can Patch Blank() values but how to delete attachments or Image fields.
Patch function does not support attachments. Form control or flow is your other options.
Image column can be patched. To make values blank with patch - ruclips.net/user/shortsfg-4nu_amJI?si=i9y5dZJalZZae5XE
This is a game changer for me. Thank you Reza
Most welcome
So, If we attach the named Formula to a gallery component will it automatically refresh or we have to manually refresh it.
It will auto refresh when user lands on the page having the gallery or a filter or reset action is initiated.
@@RezaDorranigot it. Thanks for the super fast response.
Useful for me Reza... Thanks for sharing...!
Glad it was helpful!

I have not come across this issue and hence not sure what the cause for it could be.

Hello there, I am trying to load more than 2000 records into a table in a named formula section using forall but can't achieve that. Appreciate your help
ForAll is NOT a delegable function.
Best to follow best practices and work with delegation - watch ruclips.net/video/2cKcylsGlPg/видео.htmlsi=VxmN0FnKcMdLcPfB
@@RezaDorrani Sure - anyother suggestion how to load the 3 iterration of 2000 records each into 1 table but not as a collection (managed to do that in the onstart function) but was really happy to move most of my funcitons to formulas after watching this video
Why do u need to load all data at once?
If your query is delegable, as you scroll through the results it will load all the data.
Because the query is not delegable, hence I'm trying to load it all.
@@fr.minabarsoum8528 That will impact app performance in a big way and not recommended.
very cool! I don't need refresh icon of gallery no more. I would love to use your techniques in my App. Thank you.
Go for it!
Reza, AWESOME WORK as usual
Thank you! Cheers!
Hello sir...
I want to watch your power platform training videos...
So. How much amount i need to pay?
If you click on JOIN button on my channel on a web browser, it will show you the pricing for each tier.
Hi Reza, is named formula is GA Release or not ?
GA
when iam trying to write a named formula to a list and when i see data from name formula variables pane ,it is displaying as 0 rows
eg: nfListName='List Name' ,'List Name' is sharepoint list name. But other named formulas are assigning as you mentioned in the video
Im not sure why that would be the case
All formulas in one easy place … GAME CHANGER !!
Way easier to see where you almost duplicate formula without knowing
Glad to hear that
Great tutorial 👍👏
Thank you 👍
Hi, I came across browser crashing issue suddenly in development environment (lower Environment) with data table control where as it's working fine in production environment (higher/live environment).
I have checked both environments are having same authoring versions but why the issue in dev not in prod...?
I have no clue about this. Not something I have come across.
Reza, Can named formulas already be used in a PROD environment?
Named Formulas is generally available and should be used for production scenarios.
UDF is in preview.
very helpful bro! thanks!!
Most welcome
Very Nice Explanation Reza..
Thank you
really great video - thanks!
Glad you liked it!
Can you call power automated flows with named formulas?
Currently, No
@@RezaDorrani Ok so run The call OnStart , set the return in a variable and then Collect the collection in named formulas !?
@@steviesimsii Better to use collection in those scenarios.
Nice explanation! Thank you
You are most welcome!
How come I defined the named formula without error, but when I try to use it, it shows "unknown or unsupported function"? thanks!
No idea about that as I have not experienced this
@@RezaDorrani Oh I know - forgot to toggle the UDF on
Hii reza, is it possible to Navigate different screen if user having access then navigate to screen 1 otherwise navigate to Screen 2.
In start screen and on start property of app I am not able to Navigate screen automatically by reading my access management.. Pls provide any solution
While loading app 1st read the access, based on that navigate to particular screen

I love the idea of UDFs. Can I call a SQL Server Stored Procedure from a UDF in a Named Formula?
Sql stored procedure just got announced. I have not tried it. Give it a shot and see.
@@RezaDorrani LOL. That's a nicer way of telling people what I always tell people in forums. "What happened when YOU tried it?" I will let you know. 😊😊
@@GroverParkGeorge Always best to try it.
@@RezaDorrani It looks like SQL Server Stored Procs can't be executed in Named Formulas. 😔😔
@@GroverParkGeorge same with cloud flows.
Thanks for the early access Reza!
Most welcome
Hi Reza
how to put row limit in editable table in powerapp. like only want 10 rows in editable table .
Check firstN formula documentation
Can we do patch SharePoint list inside UDF?
Have not tried it so not sure
Excellent bro!
Thanks so much
@RezaDorrani "I have a question regarding PowerApps form mode. When I add an attachment to the form and then switch to view mode, clicking on the attachment opens it in a new tab. However, PDF and image files open in view mode as intended, while Word documents and Excel files open in edit mode. I want all file types and documents to open in view mode when clicked on in a new tab". Clear the doubt and make one video.
I have not experienced an issue with opening attachment based on modes hence not sure.

Last time I used User Defined Function (a few weeks ago), my canvas app wouldn't publish - it just kept trying but was never successful.
I had to roll back my changes to fix.
Has anyone successfully publish to production?
Yes, I was able to 😊
Trick is to reference data sources separately. Check the named formulas syntax I show at end of video.
Record and Table type of parameter not supported?
Currently no for UDF
TY! ☺️
