ALV Object Model
Ali Mohammed NCDOT - BSIP
Reporting using ALV GRID in 4.6C
The New Object Model – ECC 6.0
Classes – ABAP Objects 1. ABAP Objects provides an advanced level of
encapsulation that improves maintainability and stability of programs.
2. ABAP Objects allows you to instantiate multiple instances of a single class.
3. ABAP Objects greatly enhances code reuse through “inheritance” a key feature of OO .
4. ABAP Objects is the only way to use new ABAP technology – Web Dynpro ABAP etc.
5. Explicit Event handling .
6. Better Interfaces .

ABAP Class – Transaction SE24
Programming with Class / Methods
In SE38 – ABAP Editor
CL_SALV_TABLE
Two Dimensional data display in ALV_GRID form . Object orientation (OO), or to be more precise,
object-oriented programming . No screens to define , no field catalogs to create no
PBO and PAI modules , standard menu bar can be used.
More functionality for application development. Extremely fast delivery to users. A way to get used to what ABAP programming is
trending towards. Only Available in ECC 6.0 and above .
