All the built in Programs ie. standard programs provided by the SAP will start with the letters other than Z or Y.

The programs that we create shud be differentiated from built-in programs So we create it as Z or Y as the starting Letter.

you can use either Z/Y.because it is naming convention provided by the SAP for customer development.

Hi ,

SAP has defined standard namespace for Customised Program which can start with Z/Y.

SAP as a package has N Num of programs. But all those program does not fulfill the clients requirement. So, there is always a requirement to create customised objects which has a Namespace Z or Y.
