Hello all,

Can we define and implement the class in PAI while doing module pool. I want to trigger an event (to get userdefined buttons on to alv report ), when alv is displayed in PAI event.

If we can how we can go about it else is ther an alternative for that.

Regards

offcourse we <b>CAN</b> define a class .

when u right click on the program name we get option for defining and implementing class.. u can define method inside the class defintion .. u can define event inside it..

operation wihich is to be perfromed when a event is trigged is written inside the class implemention...here we implement the methods( methods which we define ine in the class definition) ..ie the operations to be perfromed...

by creating the handler of the class we can invoke the corresponding methods... inside these methods events will triggired
