Portal user ID read in abap webdynpro.

Question

Hi All,
We have developed on web dynpro application for Dealer Portal. The Dealer logs into the portal with his ID. How can we capture this Portal User ID of the Dealer in our application.
The Portal User ID and the R/3 User ID are different.
I have followed the given steps...
Step 1
Within the Main Window of your ABAP Web Dynpro application, select Inbound Plugs tab. Now double click on the Startup Plug Named 'DEFAULT' (or what ever you have called it if you have changed this since window was created).
Step 2
Within the plug method HANDLEDEFAULT Add a new importing parameter below 'WDEVENT' parameter call it IV_USER of Type UNAME.
Step 3
Now within the code section of the plug method HANDLEDEFAULT you can freely assign the value of IV_User to an attribute of your component controller. i.e. wd_comp_controller->userid = IV_USER. Alternatively you could assign it to a wdp context node / attribute.
Please note this value will not be available with the WDDOINIT of your main view as WDDOINIT method of this view is called before the window HANDLEDEFAULT method. Put your code into the method WDDOMODIFYVIEW of your main view instead.
Step 4
Double click on the webdynpro Application, within the Parameters tab add a new parameter. You should just be able to use the F4 help on the param column and select the IV_USER entry.
Step 5
Save your application nad activate your web dynpro
With the 'Content Administration' tab of your portal
Step 1
Create an iview of type ABAP Web dynpro specifying the application name as that of your created wdp (must be exactly the same).
Key information for creating iView:
Create as iView template (select template as SAP Web Dynpro iView)
namespace = sap (check service name in SICF if this is not correct)
Application Name = ZWDA_EXAMPLE(name of your wdp created in se80)
Application Parameters = IV_USER=
Step 2
Save and setup any other details required when creating any other iView
but not able toget user id .

Hi,
Why don't you use the sy-uname to get the login details of user.
Portal users are mapped to R/3 system, so using sy-uname will definitely give the user details.
Function module to get employee details by passsing user name
  CALL FUNCTION 'HR_GET_EMPLOYEES_FROM_USER'
    EXPORTING
      user               =  sy-uname
      iv_with_authority = space
    TABLES
      ee_tab            = lt_ee_tab.
  IF lt_ee_tab[] IS NOT INITIAL.
Passing employee number to export parameter
    READ TABLE lt_ee_tab INTO ls_ee_tab WITH KEY user = sy-uname.
    IF sy-subrc = 0.
      ev_pernr = ls_ee_tab-pernr.
    ELSE.
      ev_failed = gc_failed.
    ENDIF.
  ELSE.
    ev_failed = gc_failed.
  ENDIF.
Does this help?
Thanks,
Rahul
