Using Chain of commands, we can extend the logic of public and protected methods without having to use event handlers. When you wrap a method, you can also access public and protected methods, and variables of the base class.
First it goes to Standard method finds if there any extension method of same signature
and calls extension method then calls standard method if NEXT Word mentioned else
It will not execute standard method. without NEXT word call
Rules
Ex :

Ex :
[ExtensionOf(classStr(PurchLineType))]
final class PurchLineType_Extension
{
public void initFromInventTable(
InventTable _inventTable,
boolean _searchPrice,
boolean
_setAddressFromInventDim,
boolean _initDateFields,
boolean
_executeOnlyIfProductIsFullySpecified)
{
InventTable inventTable;
purchline purchlineLoc =
purchline;
if (purchlineLoc.itemId)
{
select DOMEndSupplier from inventTable
where inventTable.ItemId == purchlineLoc.ItemId;
purchlineLoc.EndSupplier =
inventTable.EndSupplier;
}
next initFromInventTable(_inventTable, _searchPrice,
_setAddressFromInventDim, _initDateFields,
_executeOnlyIfProductIsFullySpecified);
}
}
