For example if you would like to add the custom field and Action button then you can wrtie code as follows.

{
 layout
 {
 addlast(General)
 {
 field("Credit Days"; CreditDays)
 {
 CaptionML = ENU='CreditDays';

 trigger OnValidate();
 begin
 if CreditDays < 0 then
 Error('Credit Days Can not be blank');
 end;
 }
 }

 }

 actions
