SELECTION SCREEN PROGRAMMING

Selection texts are texts which are used to replace technical field names on selection-screen with custom names.

In real-time business no business user(end user) can understand technical names, they just uses the applications for the business, when ever we print a input field on selection-screen, we get technical field names by default.
PARAMETERS : P_MTART TYPE MARA-MTART. "material type input
The above code will generate below screen
