Common error – ALV Fatal Error – GUI Cannot be reached
By sampath kumar – SAP ABAP CERTIFIED
Purpose: This document details about the common problem faced by many consultants: “Fatal Error – GUI cannot be reached” in ALV Grid Control.
The problem: SAP® has provided us with some demo programs on ALV. We would use one of them in our scenario. BCALV_GRID_DEMO is the demo program provided by SAP® for ALV Grid Control. When you execute the program in foreground, you get the similar following output:
When you schedule the same program in background, your job is cancelled due to an error. Screenshot of the same is shown below:
Reason:
ALV Grid control is based on the custom controls on the screen. When the program is scheduled in background, it tries to create GUI related front-end objects and hence the error “Fatal Error – GUI cannot be reached”. This type of problem is common with all the programs that use the ALV grid control to display the output.
Solution:
Whenever we execute this type of programs in background, we should be passing a blank docking container instead of the custom container as parent to our grid control. The docking container doesn’t need any of the custom controls on the screen; instead it attaches an area to any or all of the four edges of the screen (top, left, right or bottom). The behavior of the areas in the container is determined by the sequence in which they are initialized. Docking Containers are attached to the screen from the inside out. This means that when you create a second container, it is attached to the edge of the screen, and the container that was already there is pushed outwards. Let us modify the standard program (by taking a copy of it) to enable it to execute it in background.
Following modifications have to be made:
- Define a docking container in the program
data: or_doc type ref to cl_gui_docking_container .
- At the time of creating a custom container, check if the program is being executed in background or foreground. If the program is scheduled in background, then create a docking container instead of custom container.
if cl_gui_alv_grid=>offline( ) is initial.
create object or_custom_container
exporting container_name = c_container.
create object or_grid
exporting i_parent = or_custom_container.
else .
create object or_grid
exporting i_parent = or_doc .
endif .
OO ALV WITH CONTAINERS
Introduction
As we know that a SAP Container is a control that accommodates other controls, such as the SAP Tree Control, SAP Picture Control, SAP Text edit Control, SAP Splitter Control, and so on. It manages these controls logically in a collection, and provides a physical area in which they are displayed. All controls live in a container. Since containers are themselves controls, you can nest them. There are five kinds of SAP Containers:
SAP Custom Container: display controls in an area defined on a normal screen using the Screen Painter. Class: CL_GUI_CUSTOM_CONTAINER
SAP Dialog Box Container: display controls in a modal dialog box or full screen.
Class: CL_GUI_DIALOGBOX_CONTAINER
SAP Docking Container: The SAP Docking Container allows you to attach a control to any of the four edges of a screen as a resizable screen area. You can also detach it so that it becomes an independent modal dialog box. Class: CL_GUI_DOCKING_CONTAINER
SAP Splitter Container: to display more than one control in a given area by dividing it into cells. Class: CL_GUI_SPLITTER_CONTAINER
SAP Easy Splitter Container: this container allows us to divide an area into two cells with a control in each. The cells are separated by a moveable splitter bar.
Class: CL_GUI_EASY_SPLITTER_CONTAINER.
