False positive from AS0034: Not allowed to change `InherentPermissions` property of `table` object

Please include the following with each issue:

1. Describe the bug In v1.0 of our extension we have the InherentPermissions property applied to a table object. If we try to change the value of the InherentPermissions property for this table object in a next version, then AS0034 throws the follow error diagnostic:

error AS0034: The property 'InherentPermissions' for Table '<My Table Name>' has changed from value 'RX' to value 'RmX'. This is not allowed because it will break upgrade of existing installations and dependent extensions.

Quentin Tresontani – Wednesday at 11:40 AM I agree, this looks like a bug. Can you log this on Github? Issues · microsoft/AL (github.com)

2. To Reproduce Steps to reproduce the behavior:

Have the following property values on an AL table object in the v1 version of your extension:

table 51000 ABC_MyTable
{
    Access = Public;
    Caption = 'My Table';
    DataPerCompany = false;
    InherentPermissions = RX;

    fields
    {
        field(1; Code; Code[20])
        {
            Caption = 'Code';
            DataClassification = CustomerContent;
            NotBlank = true;
        }
        field(2; Description; Text[250])
        {
            Caption = 'Description';
            DataClassification = CustomerContent;
        }
    }

    keys
    {
        key(PK; Code)
        {
            Clustered = true;
        }
    }
}

In a v2 of your extension try to change the property value of the InherentPermissions property of the same table object to a different value, e.g.:

table 51000 ABC_MyTable
{
    Access = Public;
    Caption = 'My Table';
    DataPerCompany = false;
    InherentPermissions = RmX;

    fields
    {
        field(1; Code; Code[20])
        {
            Caption = 'Code';
            DataClassification = CustomerContent;
            NotBlank = true;
        }
        field(2; Description; Text[250])
        {
            Caption = 'Description';
            DataClassification = CustomerContent;
        }
    }

    keys
    {
        key(PK; Code)
        {
            Clustered = true;
        }
    }
}

Rule AS0034 (from the AppSourceCop) will raise an error diagnostic:

error AS0034: The property 'InherentPermissions' for Table 'ABC_MyTable' has changed from value 'RX' to value 'RmX'. This is not allowed because it will break upgrade of existing installations and dependent extensions.

3. Expected behavior No error diagnostic is raised by AS0034 when only the InherentPermissions is changed. This should not be considered as breaking (but of course changes should be applied with care).

4. Actual behavior An error diagnostic is raised by AS0034 when only the InherentPermissions is changed.

5. Versions:

AL Language: v12.1.887908
Visual Studio Code: 1.84.2
Business Central: N.A.
List of other Visual Studio Code extensions that you have installed: N.A.
