ALV using objects

former_member842213 — Mon, 12 Feb 2007 10:04:29 GMT

hi,

Im using the class which is mentioned below,

1)i need to display the top_of_page and end_of_page how can i do that?,

2)how could i give user defiined column headings.

for eg:for the first column ,the coumn heading is sales document number.

REPORT ZALV_SAMPLE.

types:begin of ty_final,

vbeln type vbeln_va,

matnr type matnr,

end of ty_final.

DATA:IT_FINAL TYPE TABLE OF TY_FINAL.

select vbeln matnr

FROM VBAP

INTO TABLE IT_FINAL.

********************this is the code for alv (OO concept)

DATA : R_TABLE TYPE REF TO CL_SALV_TABLE,

R_COLUMNS TYPE REF TO CL_SALV_COLUMNS,

R_COLUMN TYPE REF TO CL_SALV_COLUMN.

TRY.

CALL METHOD cl_salv_table=>factory

IMPORTING

R_SALV_TABLE = R_TABLE

CHANGING

t_table = IT_final.

CATCH CX_SALV_MSG .

ENDTRY.

R_COLUMNS = R_TABLE->GET_COLUMNS( ).

R_TABLE->DISPLAY( ).

Solution ->

1) Use standard Events in the Class - SET_TABLE_FOR_FIRST_DISPLAY

2)To give user defiined column headings.

for eg:for the first column ,the coumn heading is sales document number. Use text-elements or 'Hard code text' in the report.

NOTE -> In the code below, Instead of Sample text 1, 2, 3... you can type ur text.

Sample Code -

*&---------------------------------------------------------------------*
*& Report  Z_ATUL
*&
*&---------------------------------------------------------------------*
*&
*&
*&---------------------------------------------------------------------*

report  z_atul no standard page heading .
