Hi,

I thought to have a ready code and share with all, this will help anyone who is dealing with ALV in Web dynpro ABAP.

Please find the below working and tested code.
The code will allow you to change the description of the columns, Hide/display standard functions buttons, use standard function like adding etc. Have a look at the code below. Let me know in case of any further queries.

****ALV standard declarations

    DATA: LO_CMP_USAGE TYPE REF TO IF_WD_COMPONENT_USAGE,
          LO_INTERFACECONTROLLER TYPE REF TO IWCI_SALV_WD_TABLE,
          LV_VALUE TYPE REF TO CL_SALV_WD_CONFIG_TABLE.

    DATA: LR_COLUMN_SETTINGS TYPE REF TO IF_SALV_WD_COLUMN_SETTINGS,
          LR_COLUMN          TYPE REF TO CL_SALV_WD_COLUMN,
