# SORDERLINE is usually a child class of SORDER (instance is MYORDER)
$CONTROL_VAT
  # Access to a property of the instance (VAT) and another instance (snapshot) having the same properties
  If This.VAT<>This.snapshot.VAT : # The VAT value is no more the VAT value when data was read for update
     # Let's be sure the class is used as a child class
     If This.APARENT<>null
        # Is the parent class really SORDER?
        If This.APARENT.Objecttype="SORDER"
          # Access to a property in the SORDER class by using APARENT instance (a default VAT rule)
          If This.VAT<>This.APARENT.DEFAULT_VAT
            # Check consistency between VAT and header VAT (function)
            ERROR=Func(This.VAT,This.APARENT.DEFAULT_VAT)
            ...
