READ LINE

Former Member — Sat, 03 Feb 2007 11:38:20 GMT

i am in the learning of Interactive Events.. the assignment was create a classic report with checkboxes. if the user select the number of checkboxes in the basic list, the respective records should show into the secondary list with some other details.

i have done this above assignment without using checkboxes. if the user click any specific line, the secondary list will display with the respective records details. i had used with the help of HIDE keyword.

now i am not able to do the same program with checkboxex. i have found that it can be done through the READ LINE statement. can anyone help me out if u understand my prob.

Hi ashraf,

you must be having a field relating to checkbox in your internal table used for display.When you double click a line At line selection event is triggerd.

Loop at your internal table and collect all the records having checkbox = 'X' and display those.

Thank you.

Awrd points if found useful.

Hi,

You can use the READ LINE statement. The content of each line read will be in SY-LISEL. First know the position (column no.) of the checkbox in debug mode. Then read all the lines you have displayed using an index with read line. Move only those lines to another internal table which have checkbox value = 'X'. Then display their details in the subsequent screen.

Pleas check the code:

Report zsri_try.

DATA: date TYPE d,

flag(1) TYPE c,

wa(10) TYPE c.

START-OF-SELECTION.

date = sy-datum.

DO 10 TIMES.

date = date + sy-index.

WRITE: / flag AS CHECKBOX, (10) date.

ENDDO.

AT LINE-SELECTION.

DO.

READ LINE sy-index FIELD VALUE flag

date INTO wa.

IF sy-subrc <> 0.

EXIT.

ELSEIF flag = 'X'.

WRITE / wa.

ENDIF.

ENDDO.

Thank you.

hi ashraf...

I guess this would solve your problem....

REPORT demo_list_modify_field_format NO STANDARD PAGE HEADING.

DATA: box(1) TYPE c, lines TYPE i, num(1) TYPE c.

SET PF-STATUS 'CHECK'.

DO 5 TIMES.

num = sy-index.

WRITE: / box AS CHECKBOX, 'Line', num.

HIDE: box, num.

ENDDO.

lines = sy-linno.

TOP-OF-PAGE.

WRITE 'Select some checkboxes'.

ULINE.

AT USER-COMMAND.

CASE sy-ucomm.

WHEN 'READ'.

SET PF-STATUS 'CHECK' EXCLUDING 'READ'.

box = space.

DO lines TIMES.

READ LINE sy-index FIELD VALUE box.

IF box = 'X'.

WRITE: / 'Line', num, 'was selected'.

box = space.

MODIFY LINE sy-index

FIELD VALUE box

FIELD FORMAT box INPUT OFF

num COLOR 6 INVERSE ON.

ENDIF.

ENDDO.

ENDCASE.

This program creates a basic list with the status CHECK. In the status CHECK, function code READ (text Read Lines) is assigned to function key F5 and to a pushbutton. The user can mark checkboxes and then choose Read Lines.

In the AT USER-COMMAND event, the system reads the lines of the list using READ LINE. It continues processing the selected lines on a secondary list. When returning to the basic list, the system deletes the marks in the checkboxes of the selected lines using MODIFY LINE and sets the format INPUT OFF to the checkboxes. In addition, it changes the format of field num.

The user can now mark only those lines that have not yet been changed.
