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 whatever 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

Logical Database Reports
Logical database is another tool for ABAP reports. Using LDB we can provide extra features for ABAP reports.
While using LDB there is no need for us to declare Parameters.
Selection-screen as they will be generated automatically.
We have to use the statement NODES in ABAP report.
If there are many tables the Performance will be slow
as all the table data will be read from top node to bottom node .
ABAP Query Reports
ABAP query is another tool for ABAP. It provides efficiency for ABAP reports. These reports are very accurate.
Transaction Code : SQ01
The advantage with ABAP QUERY is logic required for classic & interactive reports system design automatically 80%.
For ABAP QUERY handle these
SQ01 ; QUERY
SQ02 : INFOSET OR FUNCTIONAL AREA
SQ03: USER GROUP.
Report Writer
Key Concept :
Super users and end users can use Report Painter/Report Writer tools to write their own reports.
Giving them the ability to report on additional fields at their discretion shifts the report maintenance burden to them, saving SAP support groups time and effort normally spent creating and maintaining the reports.
Instead of using ABAP code to write a report in FI and CO, many users build a Report Painter/ Report Writer library using transaction MC27.
However, this workaround has some drawbacks. Little known transaction GRCT solves these problems in most cases, and eliminates the need to use transaction
MC27.
ABAP Report Types
ABAP report types are those ones available in some report's attributes screen, i.e. :
Executable program
Function group (containing function modules)
Include
Interface pool
Class pool
Module pool
Subroutine pool
Also ALV means ABAP List Viewer. Most convenient way to use it is through reuse library (cf. transaction se83) available from release 4.6 of SAP R/3.
ALV is available in two modes: list and grid. List mode is good old list processing with standard functionalities, and grid mode is using a new OCX object displaying grids.
