LC0013 for Primary Key of Setup table

[ralf-escher]

I have created a classic setup table with an (empty) primary key.
On the setup page, a record with an empty primary key is created in the OnOpenPage trigger if none exists.
However, the LinterCop rule LC0013 demands NotBlank = true for this field.

How should this be correctly implemented?

Example from the General Ledger Setup page:

    trigger OnOpenPage()
    begin
        Rec.Reset();
        if not Rec.Get() then begin
            Rec.Init();
            Rec.Insert();
        end;
        ...
    end;

The rule only warns that NotBlank should be set explicitly, so you can still set it to false. The goal is to prevent forgetting to set the property at all and then later possibly ending up with problematic empty values in the database.
From the Wiki:

There are exceptions for this, on setup tables, for example. In those cases you can either use a pragma to suppress the warning or you can set NotBlank = false. Then the warning will not show up for this field.
