Hi,

replace

cl_salv_table=>factory( EXPORTING r_container    = custom_container1
                              IMPORTING r_salv_table = gr_table
                              CHANGING t_table = gt_process ).

with

CALL METHOD cl_salv_table=>factory
                 IMPORTING r_salv_table = gr_table
                               CHANGING t_table = gt_process.

and try please

Hi,

thank you for your Answer. its work now . But the Problem is, that i need a button.

So my idea was to create a container-Object and add a eventhandler with a toolbar to this.

its not possible to add a button to alv_table. Do you have a idea? is that possible?

regards

Go back to program SALV_DEMO_TABLE_REAL_SIMPLE.  You need the display method.

hi,

thank you for you post. i use the display method, but there is an another problem. adbul wrote a correct note, but my target to have a button in the grid is not reached.

thank you and bye
