Fast and Easy way
As you are using OO ALV, remove any function not needed from the ALV via parameter IT_TOOLBAR_EXCLUDING of method set_table_for_first_display and put your own function in the menu of your dynpro PBO via SET PF-STATUS.
Nethertheless you can use a more complew way using :
<b>Changing Standard Functions</b>
Purpose
The standard functions are not designed for specific applications. As a result, special knowledge of the data displayed cannot be considered. In individual cases, you may design a standard function - such as sorting by a specific column - more effectively in a specific application.
Process Flow
1. Define an event handler method for event before_user_command [Page 108]. This event is triggered after the user has selected a function. This means that the ALV Grid Control passes control to the application before the function is executed. Using event parameter I_UCOMM you can restrict the function code to the function you want to modify.
2. Implement your own algorithm for the function within the event handler method. In this context, you can call methods of the ALV Grid Control.
3. Reset the function code to ensure that the standard function is no longer executed:
CALL METHOD <Instance of the ALV Ccntrol>->set_user_command exporting I_UCOMM = SPACE.
If you never need specific functions of the tool bar, you can hide them for the entire life-cycle of the control. To do this, you use parameter IT_TOOLBAR_EXCLUDING of method set_table_for_first_display  to pass a table that contains the function codes to be hidden.
<b>Defining GUI Elements in the Toolbar</b>
Process Flow
1. Define an event handler method for event TOOLBAR.
2. Declare a structure for defining a toolbar element:
data: ls_toolbar TYPE stb_button.
3. For a pushbutton, for example, you would fill the following fields:
CLEAR ls_toolbar. MOVE 0 TO ls_toolbar-butn_type.
MOVE 'BOOKINGS' TO ls_toolbar-function.
MOVE icon_employee TO ls_toolbar-icon.
MOVE 'Show Bookings'(111) TO ls_toolbar-quickinfo. MOVE SPACE TO ls_toolbar-disabled.
In the butn_type field, you specify the type of the GUI element for the ALV Grid Control. For possible values, see the value range of domain TB_BTYPE.
4. Use event parameter E_OBJECT to append the new definition to table mt_toolbar:
APPEND ls_toolbar TO e_object->mt_toolbar.
5. If you want to define additional elements, go back to step 3.
6. Call method set_toolbar_interactive, if you want to rebuild the toolbar.
Result
In the event handler method of event USER_COMMAND, you can query the function code you specified in field function to implement the associated function.
