Hi everyone, I'm new to Power Apps and I have a problem with using the Patch command. The error is: the function has no valid arguments.
However, I don't understand which ones, attaching an image: TANKS!

    Hi ME-12101541-0
     
    This will be the cause of the problem.
     
    The Materiali table must have a primary key defined in SQL Server. If there is no primary key, Power Apps cannot write to the table.
     
    Therefore, the answer is to define/add a primary key column to the Materiali table. You will then need to refresh the table in the Data panel in Power Apps. At that point, the error message should disappear.
