Call URL with SSO details

Experts,

I am calling a WDA application URL using code as below,

CALL METHOD cl_wd_utilities=>construct_wd_url

  EXPORTING

    application_name = 'ZAPP1' --> Name of my application

  IMPORTING

    out_absolute_url = lv_url_str.

SSO has been enabled but still it prompts the user to enter user id & password.

Is it possible to skip this step by passing logon credentials while calling the URL from our program.

Thanks,

Aspire
