ABAP Tutorials

Following ABAP HR program is used to display a list of all the Infotype structures maintaine in the SAP. The program generates an ALV Grid which lists all the infotypes in the system.

ABAP Code:

* Calling the ALV screen with custom container
  CALL SCREEN 0600.
*On this statement double click it takes you to the screen painter SE51.
*Enter the attributes
*Create a Custom container and name it CC_CONT and OK code as OK_CODE.
*Save check and Activate the screen painter.
*Now a normal screen with number 600 is created which holds the ALV
*grid. PBO of the actual screen , Here we can give a title and

Steps to be followed:

1. Assign PNP as Logical Database in Program Attributes.

2. Create screen (0600) and write following code in its flow logic.
PROCESS BEFORE OUTPUT.
MODULE STATUS_0600.
MODULE alv_grid.

PROCESS AFTER INPUT.
MODULE exit AT EXIT-COMMAND.
MODULE USER_COMMAND_0600.

3. Place a custom container on the screen with name CC_CONT and also assign OK_CODE name to OK type. (both in Element List – > General Attributes).

4. Create PBO elements (PF Status, Titlebar).

5. Activate and execute the program.
