Problem when 2 apps are sharing the same SharePoint list data

[Englishweb]

Has anyone experienced a problem when sharing data between 2 apps from the same SharePoint list?

I’m having problems populating a dropdown control in the 2nd app from a sharepoint list which is being written to by the first app.

What could I be doing wrong  wrong ? (I've checked the obvious permissions levels and other dropdown controls are working fine)

Thanks!

I have multiple apps which access the same SP lists with no issues.  Please share more specifics of the problem you are having, including screen shots if possible, and we'll try to provide further assistance.

Hello @LRVinNC 
Thanks for the quick reply - I should add that the dropdown works perfectly for ME but not for other users.
In the first app patch to sp list "StudentsList": Patch(StudentsList,Defaults(StudentsList),{Title:S1EmailConcat.Text,CurrentStudents:S1StudentNameConcat.Text});

In the 2nd app: Dropdown 1= 
Sort(Distinct(StudentsList,CurrentStudents),Result)

Other users who are sharing both apps don't see anything in the top dropdown, however the second dropdown works fine for everyone (data from a separate sp list)

What could be blocking the first one?

Thanks

Hmmm... the fact that it does work for you does sound more like a permission issue than anything else.  I don't see any obvious issues with your dropdown and if it is working for you that would indicate the syntax is correct.    

To debug, you might simplify the dropdown (no sort, or no distinct, or neither) temporarily or try using a different column on the same list.  Or you might try putting the same data into a gallery (first just the field, then add distinct and sort) to see if they can see the data at all.  That would help further isolate the cause.

Hi @Englishweb ,

That sounds like the users don't have enough permission to read items created by other users?

Could you go to check the Item Level Permissions in SharePoint?

1. go to List Settings > Advanced Settings.

2. check Item Level Permissions section.

3. check 'Read all items' and 'Create and edit all items'.

Best regards,

Sik
