Hi,
Little advice please I want to add a Drop Down field to Item Reference table by extending the table, My code is below

tableextension 50101 MVFItemReference extends "Item Reference"
{
    fields
    {
        field(50101; "TariffNo"; Text[100]) { }
    }

    fieldgroups
    {
        addlast(DropDown; TariffNo) { }
    }

}

//Page Extenison

pageextension 50101 MVFItemReferenceEntries extends "Item Reference Entries"
{
   
   layout
   {
   addafter("Reference No.")
        {
            field("CN Code"; Rec."TariffNo")
            {
                ApplicationArea = All;
                ToolTip = 'Commodity Code from Item Referance';
            }


        }

   }
      
}

But I am getting the below error when trying to deploy to BC "error AL0513: The FieldGroup 'DropDown' is not found in the target 'Item Reference' "

Hope this helps.

Even i am not getting any error during deploying time.

Suggestion: uninstall extension from the BC, Download symbol again and then increase the application ID and then try to publish code.

The error happens because the Item Reference table in BC 19.3 doesn’t have a predefined DropDown field group, and you can’t create new field groups in this version. The workaround is to add the field directly to the page using a page extension. Alternatively, upgrading to BC 23 or later allows defining new field groups dynamically.
