Hi ,

Actually I am doing

cl_salv_table=>factory(

EXPORTING

list_display = if_salv_c_bool_sap=>true

IMPORTING

r_salv_table = gr_table

CHANGING

t_table = it_final2 ).

gr_functions = gr_table->get_functions( ).

gr_functions->set_all( abap_true ).

gr_table->get_columns( 1 ).

gr_table->display( ).

please tell me how to get header in the output

Hi,

You can exclude a column from ALV display using the method SET_VISIBLE of the class CL_SALV_TABLE.

Try this source code.

**-Variable Declaration.

DATA: IT_SFLIGHT type table of SFLIGHT,

R_TABLE type ref to CL_SALV_TABLE,

R_FUNC type ref to CL_SALV_FUNCTIONS,

R_COLS type ref to CL_SALV_COLUMNS_TABLE,

R_COL type ref to CL_SALV_COLUMN_TABLE.

START-OF-SELECTION.

Select * from SFIGHT into table IT_SFLIGHT.

**Call the class method factory method in TRY ENDTRY block.

TRY.

CALL METHOD cl_salv_table=>factory

IMPORTING

r_salv_table = r_table

CHANGING

c_table = it_sfilght.

CATCH cx_salv_msg .

ENDTRY.

r_func = r_table->get_functions( ).

r_func->set_all( Abap_True ).

r_cols = r_table->get_columns( ).

r_col ?= r_cols->Get_Column( 'XXX' ).

***---'XXX' is the name of the column you want to exclude suppose 'SEATSMAX' in SFLIGHT table.

r_col->SET_VISIBLE( abap_false ).

r_table->display( ).

I believe that this can satisfy the requirement.

Please check.

Khushboo.

Try to find out the parameter which takes the value as sel-text. It is similar to normal ALV.U will pass the value as heading there.

Hi ,

For the Header use

DATA: r_column_table TYPE REF TO cl_salv_column_table.

DATA: lr_grid TYPE REF TO cl_salv_form_layout_grid.

CREATE OBJECT lr_grid.

lr_grid->create_text(

row = 1

column = 1

text = 'Header Line 1' ).

lr_grid->create_text(

row = 2

column = 1

text = 'Header Line 2' ).

r_header = lr_grid.

With this u can define your own header names for the columns.

If you want to use table header names itself.

can use this,

DATA: r_display TYPE REF TO cl_salv_display_settings.

r_columns_table = r_table->get_columns( ).

r_columns_table->set_headers_visible( abap_true ).

where r_columns_table is ref variable of class cl_salv_columns_table.

Just check this one.

Khushboo
