Adding buttons to ALV report

Question

I am using CL_SALV_TABLE to generate a report. How do I add custom buttons on the application toolbar? Is this done in the menu or screen painter? I have not created any screens yet as I want it to remain a simple ALV report.

Answer 1

First create a PF status: We need to create a PF status with our own buttons as well as the ALV standard buttons. If we don't add the ALV buttons than it would not provide the standard functions of ALVs. On the other hand it is very tedious to add all the ALV buttons in our PF status manually. So here is the easy way: We will copy the PF-Status using of any standard SALV_DEMO report using the transaction SE41: Menu Painter. After Copying the PF-Status we can add our own buttons.
Call Method of SALV to display PF: Now we will call this newly created PF status in our ALV using the method SET_SCREEN_STATUS of the reference of the class CL_SALV_TABLE
In this section we will define the private methods which can be implemented to set the properties of the ALV and can be      called in the
PRIVATE SECTION.    METHODS:     
set_pf_status     CHANGING    co_alv TYPE REF TO cl_salv_table.
In this area we will call the methods which will set the  different properties to the ALV   
CALL METHOD set_pf_status      CHANGING        co_alv = o_alv.
In this area we will implement the methods which are defined in  the class definition
  METHOD set_pf_status.
  Calling method to set the PF-Status  
co_alv->set_screen_status(
    pfstatus      =  'SALV_STANDARD'    
   report        =  'SALV_DEMO_TABLE_SELECTIONS'    
   set_functions = co_alv->c_functions_all ).
  ENDMETHOD.                  "set_pf_status
