Making a field that is in the base application mandatory.

I am trying to make certain fields mandatory in the Sales Header. These fields are in the base application so I cant just add the field and make it mandatory. I also researched and found that you cannot modify the field in a extension to make mandatory. For example, I can't make a table or page extension and modify a field to NotBlank = true. Also at the same time I cannot find some of the fields when I open the Page Inspection, like Customer PO no., My question is how do I, in the code, make a field mandatory that Microsoft has created? I did create this in a table extension, but I am not sure if it correct.

tableextension 90000 /BLP Sales Header Extension/ extends /Sales Header/

{

fields

{

// Add changes to table fields here

modify(/Requested Delivery Date/)

{

trigger OnBeforeValidate()

begin

if /Requested Delivery Date/ = 0D then

Error('Requested Delivery Date is mandatory.')

end;
