Great Video Shane. This helped me improve the performance of my apps. I also noticed how extra loading that Powerapps is doing in my app in the background on screens that are not visible.
Thank you for another helpful video! I have actually been using the Patch(datasource, collection) function for the past few years after I learned it from your video "PowerApps Save Data - Patch, Collect, and ForAll" that you posted in October of 2018. In your Halloween app you referenced it as the "Save - Easy Way" to upload data into the data source. I have used it ever since and was glad to see it again to help reinforce that it is faster than some of the other methods I have tried. Thank you for all the great tips!
Awesome - thanks a lot! I already changed my Collect(Datasource,Collection) with Patch(Datasource,Collection) in a few apps and it works much better/faster!
Hey Shane I have managed to get the bulk patch working by using update if (containing the changes) then patch (collection to source) but I have an error thrown up. “Network error, field is read only” this I think is the ID column. It does patch the relevant data though so I could ignore this or would advise fixing? I have tried the Show Column function with ID and the columns I want to edit and it starts to patch but takes forever, I think it is patching the entire source of 9k records. I have been resetting the app to get out of it and can see the updates. Not sure what I’m doing wrong.
Double check you don't have any other required fields. I have never ID cause that error. Maybe try a much smaller size, like 3 records. And just try dropping different columns and see if you can get one to flag. Also, if you look in Monitor you might see a more detailed error. Sorry I don't have a more concrete answer. Thanks for the support. 👍
This was a great video, very informative. Good to know how some things have been described as faster when they aren’t. I’ve been using patching to the collection any changes and then patching the whole collection to the data source at once. That way I’m only hitting my external data source once
Thank you Shane. I gained a lot from this video especially the patch function discovered by Matthew. I am also curious to know which functions are your favourite top 2 since WIth function is the third on your list
I knew someone would make me think and answer that. Not exactly sure so here they are in no particular order. Patch, ForAll, With, Sequence, Mod, AddColumns :)
Awesome Shane! Thanks for this vid! One question: if you pulled your collection via Power Automate with no metadata, would you still be able to patch as a collection? I'm guessing not because Power Apps won't be able to match the schema?
Great to see this compare between Sharepoint, SQL and Dataverse, Shane. And bringing in monitor is also top-notch. Matthew's site is really packed with useful stuff and great insights.
@@ShanesCows I have an app, where the Collect(orderlines , neworderlines ) towards a sharepoint just works, but the Patch(orderlines , neworderlines ) says I'm making a syntax error, and that the second collection must be a record. =:-/ going to find that app now and see if your video helps me fix this. :-)
@@michelhegeraat5430 try Patch(orderlines, defaults(orderlines), neworderlines). it may not be what you're looking for, but that should be the syntax error resolved.
@@fortuneuji Thanks for thinking along. I found the issue. I still had 2 extra columns in the second collection. Using a DropColumn() to take them out and it just works. Microsoft error messages are so,…… I teach my kids: if you know something, speak, if you don’t, STFU. Can someone teach this to Microsoft? @shane young ?
Shane did mention in the video that this Patch(stuff, newstuff) is not documented, and I think a reason for that is, whatever is happening under the hood, the PowerApps web studio can't decipher the syntax requirements fast enough in cases where functions can take many different forms. I've had the case where I wrote Patch(stuff, defaults(stuff), newstuff) and it works fine... until two days later I open the studio to edit an entirely different part of the app. Switching it to Patch(stuff, newstuff) was how I discovered this syntax for myself. A mild but annoying case of schrödinger's bug.
This is nice Shane. I'll also like you to get your thought on a Purchase Requisition app i'm working on, I've been unable to post my line items into my Purchase Requisition Line although the headers are posting just fine and i've tried using the patch, Collect and Update function and none seems to be giving the result i want. Any ideas on how to go around this would be really helpful. I'm using NAV connector btw
Your videos are all excellent but it takes me hours to watch each one as I keep having to switch back and forth to my real world problems and put the video into practise. Thanks for your insight its definitely making me a better PowerApp'er
Thanks for this and highlighting Matthew's blog which I use regularly. I have a question - if I have a large set of records and I am only updating a few of these, would you recommend inserting a filter within the patch so it ignores the ones that haven't changed.
Looks like when sharepoint lookup columns are used as part of the collection to be bulk patched as new records, powerapps throws an error that it needs the ID. I tried both dropping the ID column, and updating the IDs to blank in the collection before running the patch(source, collection). ForAll still works, just far slower than I was hoping for. Sounds like others are getting similar results.
This is massive! Thank you Shane. I work with folks in low connectivity areas so syncing performance has always been a massive issue. For the Patch(Dataverse, Collection) is there a need to ensure that all columns are downloaded in the collection to work properly or can you use the option to only call on used columns?
He Shane, do collect instead of forall + patch will be faster. Not because of the number of post, but because of how the formula works. At the end all code will be converted to JS/TS and will call functions in the backend. There will be a function which is called lasts and this will get a table or multiple times one record.
What is the best practice to join/merge related lists (parent/child) on sharepoint into one master table in power apps? ? My lookUp columns make my power apps so slow. I’ve mitigated with a spinning wheel, but my collections can take a full minute to load. I know it’s my poorly written functions. Any suggestions?
Elizabeth I would have to see your formula to know if there is a faster way. Sometime this is, sometimes there is not. Relationships can be slow, hard work, just like in real life. 😊
@@ShanesCows I would be so embarrassed for you to see it 🤦♀️. But the load times are over 1 min, so it needs help. If you are willing to take a look, I’m willing to send it your way. I have a master list of people and a master list of trips. I filter children lists based on people assigned to certain trips- so I “joined” all of my related lists data to my “people assigned to trips” list so I could filter their data (equipment sizes, PII, etc) based on the trips they are on at any given point.
Hi I want to know is there any feature or way in power apps to enable sleep feature in power app application I am trying to use timer but I want to trigger timer if the curser is not moved for some time or app open for some time and not used. It will be really helpfull I tried to search but didn't got any answers.
@@ShanesCows I mean it really - the whole patching by ID thing, it's gonna enhance my apps across the board and for some reason it's so poorly advertised by MS that you can do that!! Brilliant thank you Shane for what you're doing.
Hey Shane, Came across an issue clearing a People column in SharePoint using patch. Ended up having to enable the experimental feature 'formula-Level error management' which i wasn't super keen on), which i was then able to patch a blank() to the people column. Have you heard of this \ got another solution?
Hi Sam - Nope that is the only way to patch a blank value back to a data source. 😑 I am also not a super fan of it, that is why no video, but I do have to use it from time to time.
Hi Shane, your videos are excellent, especially your intro :) I am trying to make a voting app using the rating control. Struggling now after successfully creating the apps and patching also works fine. Trying to lock the rating control, but it is auto-resetting, I thought of a workaround by just removing the data card after submission and moving to the next data card, but I cannot figure it out.
Thanks for the video, so helpful. I watched the "With" video to so now I understand how I should be using it. I am struggling with using Patch(DataVerseTable, Defaults(Collection)) I get this error “The specified column ‘ContainerNo’ does not exist. The column with the most similar name is ‘ContainerNo’. Following Matthew's blog on this I then tried to create an empty collection. I initially tried ClearCollect(cltBFCameraPics, FirstN(QPContainerPhotos,0)) but I get an error “The function ‘ClearCollect’ has some invalid arguments. I then tried using ShowColumns to retrieve the specific columns but they are the ‘Name’ rather than the DisplayName so they don’t match up anyway. Do you have any suggestions?
Hi Shane. I think Patch(DatasourceColumn,Collection) method will not work if DatasourceColumn will have at least one lookup column. As an example i am talking about dataverse. Am i right?
Have you ever messed with patching lookup fields using collections? I always get an error when using a collection to patch in Dataverse. No matter which "version" of the column name you use in the collection it seems to not recognize it. I even tried using the "@odata.bind" column by looking at the response of a different patch. Says the system is only allowed to populate the odata column.

Great video. Just as a note, unfortunately, Patch(dataSource, collection) doesn't work if you use AddColumns. Otherwise, it's a great hack.
Thanks a LOT!
you don't need a collection to patch multiple records all at once, just reverse your logic, instead of nesting Patch in a ForAll, nest ForAll in Patch
Clever, I like it. :)

I have not. I will make a mental note next time I am playing to try to look. In my head it is possible but I don't have a quick answer for it. Sorry.
