PowerApps application for On Premises Oracle Table

[aaedla]

Hi,

I am developing PowerApps application for Oracle ON Premises Table A for CRUD operations. This Table already has more than 2000 records and count will go on as users create more requests using PowerApps application.  

Created data connection using gateway and added canvas app and I can see Browse screen and Detail screen on left pane but Edit screen is missing. 

When I tried with Table B(Which has only 5 records), I got Edit, Browse and Detail screens and I am able to update the records. 

So my question is, why am I missing the Edit screen for Table A?Is this permission issue or something else? Are there any limitations for Oracle Database?

What kind of precautions do I need to take? I do have more than 200 columns in the table meaning 200 controls for application as well. so Is using an Oracle database a good idea? Any concerns? What kind of challenges I may face?

Thank you.

Hi @aaedla 

Is there a primary key on table A? The abscence of a primary key on a database table is the thing that usually prevents the creation of an edit screen.
