The values of ALV are not kept

[Former Member]

Dear friends,

I developed an ALV, and the quantity colum can be editable, but when I change the quantity without clicking "Check" or "Refresh" button and directly click "Save" button, the old values are displayed again - not what I have input (the new value) just at that time. Does anybody have some solution to save the new value just by clicking the "Save" button only?

Thanks a lot!!

Hi,

Below code will save the changes you made in the screen.

DATA: lv_ref TYPE REF TO cl_gui_alv_grid.

IF ucomm EQ 'SAVE'.

CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'

IMPORTING

e_grid = lv_ref.

CALL METHOD lv_ref->check_changed_data.

ENDIF.

Thanks,

Hi, the program was down when I use this method.

it said:

Short text

Zugriff über 'NULL' Objektreferenz nicht möglich.

Error analysis

An exception occurred that is explained in detail below.

The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not

caught in

procedure "OK_CODE_SET" "(FORM)", nor was it propagated by a RAISING clause.

Since the caller of the procedure could not have anticipated that the

exception would occur, the current program is terminated.

The reason for the exception is:

Es wurde versucht mit einer 'NULL' Objektreferenz (zeigt auf 'nichts')

auf eine Komponente zuzugreifen (Variable: "GO_ALV_GRID").

Eine Objektreferenz muß auf ein Objekt (eine Instanz einer Klasse)

zeigen, bevor man sie zum Zugriff auf Komponenten nutzen kann.

Entweder die Referenz wurde noch nie gesetzt, oder sie wurde mit

einer CLEAR Anweisung auf 'NULL' gesetzt.

Hi,

In my case i have used the same code which i gave you in my previous thread and it didnt throw me any dump. Just try the below code.

Try using

CREATE OBJECT lv_ref.

after it is declared.

Thanks,

Modify your internal table in the event-> AT USER-COMMAND.

case sy-ucomm.

when 'SAVE'.

MODIFY internal table.

perform Display.

Form Display. -> COntains Funtion Module or Method that Displays the ALV

Hi,

Your internal table itself is not having the updated data.

In PAI (User command), call the method CHECK_CHANGED_DATA. This method will refresh your internal table with the value available in ALV. Again use REFRESH_TABLE_DISPLAY to display the values in your internal table to the ALV on screen. This method can be called after saving the values.

Thanks,

Lakshmi
