HI,
Classical Reports Edit section
These are the most simple reports. Programmers learn this one first. It is just an output of data using the Write statement inside a loop.
Classical reports are normal reports. These reports are not having any sub reports. IT IS HAVING ONLY ONE SCREEN/LIST FOR OUTPUT.
Events In Classical Reports.
INTIALIZATION: This event triggers before selection screen display.
AT-SELECTION-SCREEN: This event triggers after proccesing user input still selection screen is in active mode.
START OF SELECTION: Start of selection screen triggers after proceesing selection screen.
END-OF-SELECTION : It is for Logical Database Reporting.
Interactive ReportsEdit section
As the name suggests, the user can Interact with the report. We can have a drill down into the report data. For example, Column one of the report displays the material numbers, and the user feels that he needs some more specific data about the vendor for that material, he can HIDE that data under those material numbers. And when the user clicks the material number, another report (actually sub report/secondary list) which displays the vendor details will be displayed.
We can have a basic list (number starts from 0) and 20 secondary lists (1 to 21). Events associated with Interactive Reports are: 1. AT LINE-SELECTION 2. AT USER-COMMAND 3. AT PF<key> 4. TOP-OF-PAGE DURING LINE-SELECTION. HIDE statement holds the data to be displayed in the secondary list. sy-lisel : contains data of the selected line. sy-lsind : contains the level of report (from 0 to 21)
Interactive Report Events:
AT LINE-SELECTION : This Event triggers when we double click a line on the list, when the event is triggered a new sublist is going to be generated. Under this event what ever the statements that are been return will be displayed on newly generated sublist.
AT PFn: For predefined function keys...
