Hey,
I have a problem in changing my Applications connection to another SharePoint list.
First let me tell you about my App:
I have reporting App which Users reports different numeral and text inputs to App. App is linked to export the data to a SharePoint list. App has three screens: Reports, New reporting and Edit report. New reporting screen creates new row in SharePoint list and all variables are saved to one row. Edit screen edits row which is uploaded earlier. There is also Reports screen where you can see all items which are reported earlier.
I am new with PowerApps and I got a responsible to maintain this application, when my colleague changed employer. Now I'm trying to create test environment, that I can develop the App without breaking working App.
Variables uploaded by users are saved to SharePoint list by Forms and each variable has own Card. I guess I was able to change new report screens connection to new SharePoint list, that it saves new report to new list.
Now I have a problem in changing edit screens connection. I tried to change connection same way than in new report screens forms from "properties"->"data source", but it doesn't work it gives an error: "Invalid formula.
Expected a value compatible with 'Data Source'." I am sure that App doesn’t get data from test list, because overall Screen shoes all items in official list. All columns are named same way in new and original SharePoint list.
Can I somehow change one cards connection separately and how can I change the connection to new SharePoint list?
All help is needed!
BR,
AH
