ALV Grid in Module Pool

We can display ALV Grid by using Module Pool. Here for the Selection Screen we have to make a custom screen (Like 9001). The Grid display will be on another screen (Like 9002). The Selection Screen contains a sub screen (100) for the Select Option.

On the selection screen we have created two button DISPLAY (FCT code = DISP) and CLEAR (FCT code = CLR). The sub screen 100 will contain the Parameter of Company code and Select option of Project Definition.

Hence for the sub screen we call sub screen including program name and screen number (100) in PBO of screen 9001. Now in PAI we call the sub screen again to pass the value entered in the screen to the program.

To display two ALV Grids we have created two Custom Containers which are referenced to CL_GUI_CUSTOM_CONTAINER class in PBO of screen 9002. We also have created two Grids, referenced to CL_GUI_ALV_GRID.

After creating these objects we have to call method SET_TABLE_FOR_FIRST_DISPLAY by Grid object in PBO of screen 9002. In this method we have passed the Layout, Field catalog and the Internal Table. Here the Grid display is displayed on the screen 9002.

After displaying the Grid in screen 9002 if we click on BACK / EXIT / CANCEL button then the program will come to screen 9001 which is Selection Screen. Hence in the PAI of screen 9002, we have to call method REFRESH_TABLE_DISPLAY to refresh the ALV Grid and FREE to refresh the Custom Container. Here we also have cleared the screen fields and internal tables used.


Following is the code of the program:

Screen - 9001:

PROCESS BEFORE OUTPUT.
  MODULE status_9001.

  "Calling the Sub Screen by using Program name & Screen
  CALL SUBSCREEN sub_sel
  INCLUDING sy-repid '100'.

PROCESS AFTER INPUT.

  "Calling the Sub Screen to pass the value
  "from Sub Screen to Program
  CALL SUBSCREEN sub_sel.
  MODULE user_command_9001.


Screen - 9002:

PROCESS BEFORE OUTPUT.
  MODULE status_9002.

PROCESS AFTER INPUT.
  MODULE user_command_9002.
