Try "Leave to screen 0" instead of "call screen 1000" in your PAI

Hello Marc Altabus,

Thanks for your reply .

if i write leave to screen 0 .after that it goes to handle double click event and leading to dump .

Method call sequence .

INITIALIZATION.

* *class declaration

   DATA : lcl_storage TYPE REF TO lcl_storage.

   DATA : lcl_event   TYPE REF TO lcl_event.

   CREATE OBJECT : lcl_storage.

*-------------------------------------------------------------------------------------*

* Start of selection

*-------------------------------------------------------------------------------------*

START-OF-SELECTION.

   CALL METHOD : lcl_storage->get_mlgn,

                 lcl_storage->get_mlgt ,

                 lcl_storage->get_text,

                 lcl_storage->get_final,

                 lcl_storage->build_fieldcat,

                 lcl_storage->hotspot_click,

                 lcl_event->handle_double_click.

Dump :

An exception has occurred which is explained in more detail below. The

exception, which is assigned to class 'CX_SY_REF_IS_INITIAL' was not caught and

therefore caused a runtime error. The reason for the exception is:

You are trying to access a component with a 'ZERO' object reference

(points to 'nothing'). Variable: "LCL_EVENT".

An object reference must point to an object (an instance of a class)

before it can be used to access a component. The reference has either

never been set, or it was set to 'ZERO' with a CLEAR statement.

Seems you coded some CALL SCREEN instead of a LEAVE SCREEN (LEAVE TO SCREEN, SET SCREE or similar code)

I have used call selection-screen 1000.

[sravya_ch]

To make it more clear .

I have 3 screen's

1000-Selection screen

8889- Alv Report

8888-Model Dialog box.

If i double click on 8889 screen and go to 8888 do some action and come back .

Once i am back to 8889 screen if can go to selection screen if i write ( Call selection-screen) if i write leave screen 0 or leave screen its calling 8888 screen .

How do you handle the back button in the ALV? (PS: of course you must not use CALL SELECTION-SCREEN from your ALV to return to the selection screen, because when you leave the selection screen, you come back to the ALV)

[raymond_giuseppi]

You should have a logic like

SELECTION-SCREEN    1000

CALL SCREEN 8889     1000    8889   

CALL SCREEN 8888     1000    8889    8888

SET/LEAVE SCREEN    1000    8889   

SET/LEAVE SCREEN    1000

Remember LEAVE TO SCREEN 0 / SET SREEN 0 + LEAVE SCREEN will go to the statement following previous CALL SCREEN
