Requirement: Open Transaction code in SAP GUI from WD ABAP application

Question

Hello All,
I have a WD ABAP application which is accessed from SAP GUI and Portal. In SAP GUI, there is report which calls the application URL.
In the WD application, I need to call a transaction code. At this juncture, I made use of the ITS url. But,, the SSO does not work in SAP GUI.It works only in portal.
As a solution,we identified the entry point i.e. SAP GUI or portal. Then, based on entry from SAP GUI, we tried to call the transaction code using call transaction statement. But, that replaced the wd application. We instead wanted it as a popup or atleast another session.
Now, how do we open a transaction from WD screen in another session?
Also, can we setany configurations in the system to make sure the SSO works for all the transactions i.e. ITS used in SAP GUI.?
Thank you.
Regards,
Sharath

Hi,
This question gets asked many times.
Depending on the circumstances, this can be achieved with varying degree of success
So here is some code that might help you.
This can (does) load a Windows GUI.
Some things to consider.
1. Browser settings can get in the way a bit, asking the user if they want to open a ".sap" file
2. The user may have a SAP session open so consider adding a "/o" to the system code.
3. The Custom variable might want to contain a [Options] section for "Re-use"
4. The SAPLogon_ID may be required if using SSO (SNC)
I have modified the code below, but you will get the idea.
JS
* Create the shortcut contents
  call function 'SWN_CREATE_SHORTCUT'
    exporting
      i_system_command        = lv_com
      i_saplogon_id           = lv_logon_id
      i_sysid                 = sy-sysid
      i_client                = sy-mandt
      i_user                  = sy-uname
      i_custom                = lv_custom
    importing
      shortcut_string         = lv_string
    exceptions
      inconsistent_parameters = 1
      others                  = 2.
* Convert to xstring to execute....
  call method cl_http_utility=>if_http_utility~encode_utf8
    exporting
      unencoded = lv_string
    receiving
      encoded   = lv_xstring
    exceptions
      others    = 1.
* Now call to open the shortcut.
  lv_file_name =  'mytrans.sap'.
  lv_mime = 'application/x-sapshortcut'.
  call method cl_wd_runtime_services=>attach_file_to_response
    exporting
      i_filename      = lv_file_name
      i_content       = lv_xstring
      i_mime_type     = lv_mime
      i_in_new_window = abap_true.
