CREATE EXTENSION OF TABLE WITH CHAIN OF COMMAND

Below example will help to understand how to create a table extension and within that table extension create a chain of command method .
You can also write a new method if required .eg method testmethod.

[Extensionof(tableStr(SalesTable))]
final class SalesTable_Extension                                     
 //the class must be extended by _extension and it should be decorated by extensionof(tablestr(tablename))
{
    /// <summary>
  ///
    /// </summary>
    public void modifiedField(FieldId _fieldId)
    {
        next modifiedField(_fieldId);  //the next operator needs to be placed as per the requirement
       
        if (_fieldId == fieldNum(SalesTable,ConfirmedDate))
        {
                this.ConfirmedDate= datenull();
        }
    }

    public void testmethod()
  {
            /// to some task here.
  }
}
