call selection screen and ok_code

[Former Member]

hy folks i'm trying to managing a back to selection-screen from an alv grid using the ok_code

CASE save_ok_code.
WHEN
fcode_back OR
fcode_esc.
CALL METHOD grid->free.
CALL METHOD tree1->free.
CALL METHOD g_custom_container->free.
call selection-screen 1000.
when others.
endcase.

why the flow is like this.

AT SELECTION-SCREEN.
  IF sy-ucomm = 'ONLI' or sy-ucomm = 'CRET'.
    PERFORM acquisisci_rasn.
  ENDIF.

START-OF-SELECTION.
* Initialization Drag and Drop
  PERFORM init_dragdrop.

END-OF-SELECTION.
  g_repid = sy-repid.
  CALL SCREEN 100.

....

the problem is that after backing to the selection-screen, if you excute again the program, is dumping, the container and the grid are not loaded.

what do i miss?

Hi Andre,

Write the Checks before you use any references.

eg.,

if tree1 is BOUND.

do your operations .

ELSE.

CREATE REFERENCES

ENDIF.

this may solve your problem

Hello,

I think there is some problem in your PBO logic.

AND clear the reference variable by using the Keyword FREE.

Hello Andre,

Try the following:

CASE save_ok_code.
WHEN
fcode_back OR
fcode_esc.
CALL METHOD grid->free.
CALL METHOD tree1->free.
CALL METHOD g_custom_container->free.
CLEAR: grid, tree1, g_custom_container.
call selection-screen 1000.
when others.
endcase.

Note the line: CLEAR: grid, tree1, g_custom_container.

Regards,

George

This seems to be occuring because you are not handling exceptions while calling the free method.

Try to handle the exceptions as given in below code . Then the dump can be avoided

CALL METHOD cl_grid1->free

EXCEPTIONS

cntl_error = 1

cntl_system_error = 2

OTHERS = 3.

IF sy-subrc <> 0.

• DO Nothing

ENDIF.

clear save_ok_code.  "Add this
call selection-screen 1000.
when others.
endcase.
