Re: Connecting External System with SAP ABAP Server using SNC

Hi Fillipe,

We have same issue. We have .NET application which is connecting to SAP using RFC call with connection parameters Username, pass, Host, sys no and client. Now we are enabling SNC in .NET application.SAP environment is configured with SNC (without SSO similar to Configuring SAP SNC without Single Sign-On on UNIX/Solaris/Linux) . At client side (SAP GUI) instead of SCE library file we have used Secure login client 1.0 library files and configured SNC between SAPGUI --> AS ABAP.

Same like to configure SNC between .NET application --> AS ABAP we are using additional connection parameters SNC_MODE, SNC_QOP, SNC_PARTNERNAME, SNC_LIBRARY.

but getting below issue while connecting from .net application.
