Get Windows User in ABAP - Webservice

[Former Member]

Hi all,

i need the windows user in an ABAP Webservice.

I have found many solutions (e.g. cl_gui_frontend_services->get_user_name or function modules GUI_GET_DESKTOP_INFO, WS_QUERY ....)

But these solutions are only working if you are connected via SAP GUI to the SAP system.

I want to trigger the web service not via SAP GUI.

Is there a possiblility to get the Windows user in ABAP without the need of the SAP GUI?

from which environment you are trying to read the windows user? from a web app?

• via sapgui --> use your method

• not via sapgui --> read field 'sy-uname' for sap user name. As far as i remember we didn't make a Windows user for access to a sap webservice. You only need a sap user and password to access the webservice; the calling system sends a request with sap user and password, and not necessarily any Windows involved there either.

Hope this helps,

Hi,

there is a security problem because of the different environments windows/sap.

Solution:

On the windows side i have a kerberos token for authentication. (fasade service 1)

On the sap side i use the sy-uname. (fasade service 2)

And the service which uses the fasade services is an email service.

you can get the windows logged on (network) id from a vbscript/javascript (which uses windows script host) vbscript code would look like below

Dim mynw
set mynw = createobject("WSCRIPT.Network")
dim uid
uid=mynw.UserName

if you let me know from where you are trying to get this, can come up with alternate approach. (from web application? or from some other approach)

Hi, I have the same problem - getting Windows user name from WebDynpro (ABAP). Have you any idea how to call your piece a code from there?

Thanks,

Issue: I need to determine a windows user in my WebDynpro (ABAP ) application. I do it on a following way:

Instead of calling my WebDynpro application directly I call my own BSP getuser, the link to the my WebDynpro will be transferred as page attribute <wd_url> (auto).

Important: the WebDynpro link has to be percent-encoded, e.g. the link:

[https://...../sap/bc/webdynpro/sap/z_my_webdynpro?sap-client=500&sap-language=E]

should look like as:

[http://https%3A%2F%2F.....%2Fsap%2Fbc%2Fwebdynpro%2Fsap%2Fz_my_webdynpro%3Fsap-client%3D500%26sap-language%3DE]

Example:

Call BSP

[http://.../sap/bc/bsp/sap/zcallwd/getuser.htm?wd_url=<wd_link_percent_encoded>]

BSP Flow Logic:

<form name="form1" action="<%= wd_url%>" method="POST">
<input type="hidden" name="user" type="text" value="<%= user%>">
</form>

< script language="vbScript">
Dim uname
Set ows = CreateObject("WSCRIPT.Network")
uname = ows.UserName
document.form1.user.value = uname
</script>

< script language="javascript">
document.form1.submit();
</script>

As you can see, the user will be transferred to the WebDynpro call via POST method here - as part of the data body and will not be visible in the WebDynpro URL. Instead of POST you can use GET, too, the parameter <user> will be visible in WebDynpro URL then.

I know itu2019s a little bit complicated, but it function very well.
