About table control

Former Member — Tue, 11 Sep 2007 09:38:55 GMT

Hi all,

I have create a report program, and I call a screen in it:

AT SELECTION-SCREEN.

CALL SCREEN 100.

In the screen 100, I create a table control.

PROCESS BEFORE OUTPUT.

MODULE get_data. " Get data to table it_tab

LOOP AT it_tab TO wa_tab WITH CONTROL tc_ctrl.

MODULE populate_screen.

ENDLOOP.

MODULE populate_screen OUTPUT.

DATA: ld_line TYPE i.

IF sy-stepl = 1.

tc_ctrl-lines = tc_ctrl-top_line + sy-loopc - 1.

ENDIF.

MOVE-CORRESPONDING wa_tab TO ztc_tab.

ENDMODULE. " populate_screen OUTPUT

ztc_tab is the table I used in the table control, but when I check the screen, there is an error message 'The field 'ZTC_TAB-SEL' is not assigned to a loop. 'LOOP...ENDLOOP' must appear in 'PBO' and 'PAI''. I don't know why, can anyone tell me ? Many thanks!

Hi Yu,

If not try creating it with the wizard.

hello yu_huali,

You has to loop the table which u had used in the table control.

see the below code.

***IN PBO

loop at ztc_tab

with control tc_ctrl

cursor tc_ctrl-current_line.

endloop.

***IN PAI

loop at ztc_tab.

chain.

field ztc_tab-fieldname

**all the fields that you are displaying in the table control in the ztc_tab must be in chain & endchain

endchain.

Reward if useful.

Regards,

Phani.

Yu,

First in Screen 100, create a table control and add the fields you need to display in it. Better avoid the wizard.

Second, populate it using the stx:

PROCESS BEFORE OUTPUT.

MODULE get_data. " Get data to table it_tab

The below code will set the number of lines to display based on your itab lines DESCRIBE TABLE it_tab LINES tc_ctrl-lines.

Use the below code to populate the table control

loop at it_tab into it_tab with control tc_ctrl.

endloop.

This should help. Reward if useful...

You mean I assign it_tab[] to ztc_tab[] first, then loop at ztc_tab?

what should I do in the loop?

loop at ztc_tab

with control tc_ctrl

cursor tc_ctrl-current_line.

endloop.

I create it without a wizard.
