i'm building a new class and i got an srious problem .

here's the code :

CLASS lcl_alv_control DEFINITION .

PUBLIC SECTION.

*Structure to transfer to the Alv Grid

TYPES : BEGIN OF scrdisp ,

ts_icons(30) TYPE c,

dp_icons(30) TYPE c,

symbols(30) TYPE c,

info(4) TYPE c,

colinfo TYPE lvc_t_scol ,

cellstyles TYPE lvc_t_styl ,

checkbox,
lights,

links TYPE i ,

END OF scrdisp.

DATA:

gtab_scrdisp TYPE TABLE OF scrdisp INITIAL SIZE 0 ,

gstr_scrdisp LIKE LINE OF gtab_scrdisp,

*Field Catalog for the ALV Grid

gt_fieldcat_lvc TYPE TABLE OF lvc_t_fcat INITIAL SIZE 0 ,

gs_fieldcat_lvc LIKE LINE OF gt_fieldcat_lvc ,

*Color Table for handle all the cells colors .

gt_color TYPE TABLE OF lvc_t_scol INITIAL SIZE 0 ,

gs_color LIKE LINE OF gt_color .

*Another Global Data

METHODS:

set_ctl_name ,

build_layout ,

build_fieldcat ,

set_hendlers ,

exclude_toolbar_buttons ,

display ,

build_data ,

on_double_click ,

handle_user_command ,

handle_toolbar_set .

ENDCLASS.

CLASS lcl_alv_control implementation.

method build_layout.

gs_color-fname = 'whatever'. <--- the problematic line

endmethod.

endclass.

in the implementation section when i use the gs_color structure i got error that tells me : "GS_COLOR" is a table without a header line and therefore has no component called "FNAME".

could someone can help with this ??

Hi Herzel,

You have defined gt_color as a table of lvc_t_scol. However, type lvc_t_scol is already a table. As a consequence the definition of gs_color is also a table.

Suggested correction:

gt_color TYPE lvc_t_scol,

gs_color TYPE lvc_s_scol.

Regards,

John.

gt_color is table type of lvc_t_scol

and gs_color is like line of gt_color

so why should be a problem with it ???

Again: lvc_t_scol is already a table; the way you define gt_color will create a table of a table. And thus gs_color (LIKE LINE OF) will be table also, and in OO you can not address a field in a table, you should use a falt structure.

Hello Herzel,

what John tried to explain the table defintion should be fixed not the line definition. Can you please try the following?

Best Regards

Klaus


report  kzi_test_01.

data:
  gt_Color type lvc_T_Scol,
  gs_Color like line of gt_Color.


insert gs_Color into table gt_Color.
