OOPS ALV in SAP ABAP

by

Hello Friends, if you are trying to learn OOPS ALV in SAP ABAP | OOPS ALV Report Creation in SAP | OOPS ALV Tutorial in SAP ABAP | OOPS ALV Notes in SAP ABAP | OOPS ALV Step by step creation | OOPS ALV Notes for Freshers | OOPS ALV Notes for Beginner then you learn it from here.

If we want to work on OOPS ALV then we need to create one screen, create one custom control in
it. Custom control we can not use it directly, so refer it to custom container. From Custom
Container, we can not display the data, so refer it to grid display.

OOPS ALV

CL_GUI_CUSTOM_CONTAINER:- Global Class which refer the Custom Control screen element
CL_GUI_ALV_GRID:- Global class which refer the ALV Grid.
SET_TABLE_FOR_FIRST_DISPLAY :- This is a method in CL_GUI_ALV_GRID which is used to display
the data.
If you want to call this method then we must create object for gird class. Whenever we create the
object for gird class then automatically one constructor is triggered and asks the input as object
name of container class. Whenever we create the object for container class then automatically
one constructor is triggered and asks the input as container name.

Steps to work with OOPS ALV:-

  1. Create the selection-screen / input fields.
  2. Declare the data internal table and field catalog internal table
  3. Create the reference to the container and grid class start-ofselection.
  4. Call screen & place custom control component in it.

PBO of the screen: –

  1. Design the back button
  2. Create the object to the container and gird class
  3. Fill the data internal table
  4. Fill the field catalog
  5. Call the SET_TABLE_FOR_FIRST_DISPLAY method
