AL Development in Business Central – Part 6 How to create a page extension

To create a page extension you need to define the following things:

• The page extension ID and Name
• Which page to extend
• The new fields (that exist in the table-extension for example).
• Each field should be tagged with a value for the ApplicationArea and ToolTip property. If not then the field may not be displayed in the cloud version of BC.
• More information about the ApplicationArea property can be found on Microsoft Docs: https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/developer/properties/devenv-applicationarea-property

An example:

pageextension 50101 "CustomerList Ext" extends "Customer List"
{
    layout
    {
        addafter("No.")
        {
            field(Skilled; Skilled)
            {
                ApplicationArea = All;
                ToolTipML = ENG = 'Specifies whether this customer is skilled and followed training.';
            }
        }
    }
}
