Environment

  • SAP Lumira Desktop 1.27 and higher

Reproducing the Issue

  1. In SAP Lumira, create a new document, and select "Download from SAP Business Warehouse"
  2. In the window "Download from SAP Business Warehouse", select an SAP BW Server that uses SNC, and click "Connect"
        
    It then displays the error: 
     
    "Unknown error: Connect to SAP gateway failed Connection parameters:
      TYPE=A DEST=custom_<SAP System Name> ASHOST=<Host Name> SYSNR=<System Number>
      SNC_MODE=1 SNC_QOP=9 SNC_MYNAME=" " SNC_PARTNERNAME=<SNC Patrner Name>  PCS=1 no SAP ErrInfo available"

Cause

  • The computer is not configured to connect to an SAP BW System using SNC for a 64 bit application like SAP Lumira; or
  • The SAP BW Server is not configured or incorrectly configured for using SNC.

Resolution

  • Contact your SAP BASIS Administrator to configure SNC on the local computer for the SAP BW System required. ( 64bit )
        
  • Confirm you can login successfully to the same SAP BW System from the SAP Logon that uses SNC.
         
    1. Launch the SAP Logon application.

      The SAP Logon is a 32bit application. If it successfully login to the same SAP BW System using SNC, then it confirm it is the 64bit configuration that is either not installed, or not configured on the local computer. Contact your SAP BASIS Administrator to configure the local computer with the 64bit SNC / SSO.
