alv with method set table for first display

[Former Member]

I'm trying to make an alv report using OO programming. I've already made it using the function module 'reuse_alv_list_display' and it's working propperly so my database query it's exactly the same, but whe I veryfy the sintax, the next error message appears:'gt_output is not type compatible with formal parameter it_outtab'. I don't know what's going on, because I think I've declared my parameters properly, anyway this is my source code:

DATA: grid TYPE REF TO cl_gui_alv_grid,

g_custom_container TYPE REF TO cl_gui_custom_container.

TYPES: BEGIN OF st_output,

tplnr LIKE viaufkst-tplnr,

pltxt LIKE iflo-pltxt,

acpos LIKE pmco-acpos,

END OF st_output.

DATA:gt_output TYPE STANDARD TABLE OF st_output WITH HEADER LINE.

SELECT-OPTIONS:TPLNR FOR gt_output-tplnr.

START-OF-SELECTION.

CALL SCREEN 1000.

*&----

---

*

*& Module STATUS_1000 OUTPUT

*&----

---

*

• text

*----

---

*

*creo q para hacerlo con objetos hay que definir 1º la vista, y despues

*hacer el select sobre ella, en lugar de hacer los joins en el select

*la vista que definamos se utiliza como tipo de tabla para gt_output.

MODULE STATUS_1000 OUTPUT.

• SET PF-STATUS 'xxxxxxxx'.

• SET TITLEBAR 'xxx'.

IF g_custom_container IS INITIAL.

CREATE OBJECT g_custom_container

EXPORTING

CONTAINER_NAME = 'CCCONTAINER'.

CREATE OBJECT grid

EXPORTING

I_PARENT = g_custom_container.

ENDIF.

SELECT V_{TPLNR I}PLTXT P~ACPOS

INTO CORRESPONDING FIELDS OF TABLE gt_output

FROM VIAUFKST AS V

INNER JOIN IFLO AS I

ON V_{TPLNR = I}TPLNR

INNER JOIN PMCO AS P

ON V_{OBJNR = P}OBJNR

WHERE V~TPLNR IN TPLNR.

CALL METHOD grid->set_table_for_first_display

EXPORTING I_STRUCTURE_NAME = 'st_output'

CHANGING IT_OUTTAB = gt_output.

ENDMODULE. " STATUS_1000 OUTPUT

Thanks everybody, this is a really good way to learn about ABAP programming.

Hi

U haven't to use internal table with header line, so or you define it without headerline

<b>DATA:gt_output TYPE STANDARD TABLE OF st_output.

• WITH HEADER LINE. <----------------------------</b>

or you transfer only the data:

<b>*CALL METHOD grid->set_table_for_first_display

*EXPORTING I_STRUCTURE_NAME = 'st_output'

*CHANGING IT_OUTTAB = gt_output.

CALL METHOD grid->set_table_for_first_display

EXPORTING I_STRUCTURE_NAME = 'ST_OUTPUT'

CHANGING IT_OUTTAB = GT_OUTPUT[].</b>

In ALV OOPS.You cannot use a header line with internal table.So you have to declare your table like this :

data :

gt_output type standard table of st_output .

Hello,

You have created the table gt_output[] with header line.

So while passing it it should be passed as gt_output[] and not as gt_output.

Correct this, it will work.

OK THANKS EVERYBODY!!!

Now would anybody mind to explain me what i'm doing when I write gt_output[]? what's the difference between gt_output and gt_output[]? I'm sorry but i've just started with ABAP.

Thanks!!

hi,

gt_output[] - > content of an internal tabel

gt_output - > only the header.

gt_output[] is referring the whole table content. you will see it clearly at debugging mode.

hi,

adding to the above.

for you knowledge, chk this ex.

chk this.

DATA: begin of int_table occurs 0,

field1 like table-field1,

field2 like table-field2,

end of int_table.

here an internal table with work area is created.

int_table[] - > content or body of int_table.

int_table - > work area.
