Hi Sam,

what is your intension of using this method? If you want to get the visible name from a person you can try the following code:

  data ls_address type bapiaddr3.
  data lt_return  type bapirettab.
  data ls_name    type t_user_name.

  if iv_user is initial.
    rv_name = 'Unknown'. "#EC NOTEXT
    return.
  endif.

  read table mt_user_name into ls_name
                          with table key user = iv_user.
  if sy-subrc = 0.
    rv_name = ls_name-name.
  else.
    call function 'BAPI_USER_GET_DETAIL'
      exporting
        username      = iv_user
*       CACHE_RESULTS = 'X'
      importing
        address       = ls_address
      tables
        return        = lt_return.

    rv_name = ls_address-fullname.
    ls_name-user = iv_user.
    ls_name-name = rv_name.
    insert ls_name into table mt_user_name.
  endif.

As I have to retrieve a lot of names from user data, I build up a buffer table for my own. Nevertheless, you might simply use BAPI_USER_GET_DETAIL in case you just have to get a single name.

Hope this helps,

Cheers, Daniel

You cannot use any SAP Gui frontend service in Web Dynpro, because there is no GUI available...

Hi,

      I am using this method inside a ABAP WebDynpro component. Looks like it don't work web based applications. Just wondering is there any infotype stores the Windows ID of the employee..?!

Thanks
