Multiple ALV grids on a single screen in SAP ABAP

It is not possible to resize or place the grid at a particular position using function modules as ALVs are always displayed in fullscreen when using function modules. This limitation makes it challenging when you need to display multiple ALV grids or have more control over the grid positioning.

One method to overcome this limitation is to create a screen using custom container and then use the class CL_GUI_ALV_GRID to attach the ALV grids to this container at desired positions.

Implementation Steps

To create multiple ALV grids on a single screen, follow these key steps ?

Step 1: Create a screen (dynpro) with custom container controls

Step 2: Define internal tables for your data

Step 3: Create container objects using CL_GUI_CUSTOM_CONTAINER

Step 4: Create ALV grid objects using CL_GUI_ALV_GRID

Step 5: Link the ALV grids to their respective containers

Example Code Structure

Here's a basic example showing how to implement multiple ALV grids ?

" Data declarations
DATA: lo_container1 TYPE REF TO cl_gui_custom_container,
      lo_container2 TYPE REF TO cl_gui_custom_container,
      lo_alv_grid1  TYPE REF TO cl_gui_alv_grid,
      lo_alv_grid2  TYPE REF TO cl_gui_alv_grid,
      lt_data1      TYPE TABLE OF sflight,
      lt_data2      TYPE TABLE OF spfli.

" Create containers
CREATE OBJECT lo_container1
  EXPORTING
    container_name = 'CONTAINER1'.

CREATE OBJECT lo_container2
  EXPORTING
    container_name = 'CONTAINER2'.

" Create ALV grids
CREATE OBJECT lo_alv_grid1
  EXPORTING
    i_parent = lo_container1.

CREATE OBJECT lo_alv_grid2
  EXPORTING
    i_parent = lo_container2.

" Display data in grids
CALL METHOD lo_alv_grid1->set_table_for_first_display
  CHANGING
    it_outtab = lt_data1.

CALL METHOD lo_alv_grid2->set_table_for_first_display
  CHANGING
    it_outtab = lt_data2.

Screen Design Considerations

When designing the screen, ensure that each custom container has a unique name and proper sizing. The containers should be positioned appropriately to accommodate both ALV grids without overlap.

This approach provides full control over ALV positioning and allows for sophisticated screen layouts with multiple data displays.

Conclusion

Using custom containers with CL_GUI_ALV_GRID class enables precise control over ALV grid positioning and allows multiple grids on a single screen, overcoming the fullscreen limitation of function modules.
