Interactive Reports

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:

AT LINE-SELECTION

AT USER-COMMAND

AT PF<key>

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...

AT USER-COMMAND : It provides user functions keys.

TOP-OF-PAGE DURING LINE-SELECTION :top of page event for secondary list.

In ALV reports one generally uses the ABAP LIST VIEWER for ALV grid or List Display.When using ALV there are FM's that need to be called in order to display the report in grid or list format.

Reward if useful.
