Hello,

Hoping you can help me with a couple questions in regards to collections and auto saving work.

 

1) In using collections within a canvas app, how is the data handled in regards to multiple users using the app at the same time. Do you get a collection created for each user instance? For example, I create a collection called CollectNotes that stores a 4 rows of data, and 5 users access the app at the same time. Would I have 1 collection with 20 rows or 5 separate instances. I want to be careful since I'm using clearcollect function to build it.

 

2) So my team is looking at using the meeting capture app you see in the sample apps. https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/sample-meeting-capture#:~:text=In%20Power%20Apps%2C%20the%20Meeting%20Capture%20sample%20template,pictures%20of%20whiteboards%2C%20draw%20sketches%20and%20assign%20tasks.

I'm adding more features to it but I noticed a problem when using the app in Teams. If I leave a tab and come back I lose all my data. I need a way to take the notes I entered, save it to a collection or Sharepoint list or something, and then when I go back to the meeting record it pulls up the notes. Would be cool if the notes saved as I write them like when you use OneNote but it seems that is not possible. To accommodate this it would be nice to save the record if I clicked on another area of the form or just hit a save button. But want to do my best to save as much as possible in advent app crashes or I move away in Teams.

 

Thanks

    Collections by definition are created locally in the storage of the device.  So each collection is specific to a particular user on a particular device/session.  There is no way to easily share the values in a collection between multiple users.

     

    So #1 - you would have 5 separate instances with 4 rows of data each.

     

    #2 - Sample apps are normally written using collections as the data source because they are transportable.  But in this case you want to have a more permanent data source like SharePoint behind the app.
