We can extend the logic of public and protected methods without having to use event handlers. COC, allows to use the method local and global variables. COC must be end with _Extension. Form level method : System search there are any extend methods , If Extend method is exist,run COC method first , next() method Invoke Standard form methods . Form Custom method:     [ ExtensionOf ( formstr ( CustTable ))] final class CustTableForm_Extension {     public amount getAmount( amount _amount)     {         //Here we can get buffers,Add logics and change parameter as per our business requirement.         Amount    retAmount = next getAmount(_amount);         //Here we can get buffers,Add logics and change return values as per our business requirement.          Return retAmount;     } } Get buffers :     FormRun formRun = this as   FormRun ; FormDataSource CustTable_DS =formRun.datasource(ForomDatasourceStr(CustTable,CustTable));
