In an OO transaction, you can link a transaction code to a method of a class in ABAP Objects.
To create an OO transaction, use transaction SE93 (Transaction Maintenance) or the Object Navigator.
The Object Selection dialog screen appears.
The Create Transaction dialog screen appears.
The Create OO Transaction screen appears.
If you remove this selection, you can link the transaction code to any method of a global or local class of a program. When you call up a transaction linked to an instance method, the system automatically generates an instance of the class in its own internal session (see the example under OO Transactions ).

Professional User Transactions are the standard transactions executed in the SAP system. An Easy Web Transaction is an ITS-based transaction, which can be executed only in the SAP GUI for HTML. You need to refer to an ITS service in order to use it.
The SAP GUI settings do not affect the transaction itself; they only inform the user what software is needed to start the transaction: SAP GUI for Windows, SAP GUI for Java or only the browser (SAP GUI for HTML).
