Hi,

maybe you should rewrite your report using modern approach described in the following link:

https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/eac1fa0b-0e01-0010-0990-8530de4908a6

You can find tons of questions and answers on this forum and please put your code into code tags (check on the right side Markup/Results ). The code will be easier to read. Hence chance that someone will help you will be higher.

Cheers

Hi!

where does your alv control display?

Is there a screen?

Cheers!

Former Member — Wed, 30 Apr 2008 07:50:12 GMT

Hi,

from the line if gl_alv_grid is initial.....

until last endif i.e set_table_for_first_display

this shold be in the PBO module of your screen not in start-of-slection

where is your call screen stmt???

you should define a screen, on the screen drag & drop a custiom container and give it the name 'CCALV' ehat you gave in your program.

then in the PBO write the aboe logic and in PAI if you want to handle any sy-ucomm you can do it,

see my sample program

REPORT ZSOW_OBJECT7.

ITAB TYPE TABLE OF SFLIGHT,

G_CUST TYPE REF TO CL_GUI_CUSTOM_CONTAINER,

G_GRID TYPE REF TO CL_GUI_ALV_GRID.

START-OF-SELECTION.

SELECT * FROM SFLIGHT INTO TABLE ITAB UP TO 10 ROWS.

saving a layout.

CHANGING

ENDIF.

Note: My custom container name in screen 100 is 'CUSTOM'.

Do reward points if it helps you

Hi,

Have you Activate your Custome Control

gc_custom_control_name type scrfname value 'CCALV',

Check whether you given name( custom conainer ) is correct or not , build the field catalog and append the fields.

In this Decaration

CREATE OBJECT gl_alv_grid

EXPORTING

I_SHELLSTYLE = 0
