How to call SAP BAPI function ASP. Net C# WEB API??

[vgkk]

I have created ASP.net Web API and called the SAP BAPI function. It is working fine after being hosted to a Windows server with SAP user name and password but it does not work with the Kerberos SSO after the Host the Web API in the Windows server IIS.

The Web API will call by the end user using a frontend Web application. he will insert his data into SAP with the help of ASP.Net Web API.

I need one centralized solution all users will access the Web application with SAP SSO.

My Web Application Flow :

End User (Web Browser) => Authenticate in Azure AD => Login to Web Application Portal => User Post Data to SAP system using BAPI function.

Can anyone please help me here to call the SAP BAPI function in ASP.net Web API for multiple users??

Please provide details of the configuration and SAP Software installation.

My company has implemented exactly what you describe for some of our customers, using Kerberos. So, it is possible.

Hi Tim,

Thanks for your response.

I am able to invoke the SAP BAPI function in ASP.Net C# Web API and it's working fine with username and password credentials but I don't want to implement the same with the username & password. We are passing the parameter to RfcConfigParameters class. Please see the below values.

parms.Add(RfcConfigParameters.AppServerHost, "eayqsapXXX");

parms.Add(RfcConfigParameters.LogonGroup, "SUPPORT");

parms.Add(RfcConfigParameters.SystemNumber, "25");

parms.Add(RfcConfigParameters.SystemID, "QEX");

parms.Add(RfcConfigParameters.User, "3283832");

parms.Add(RfcConfigParameters.Password, "EYTestingXXXXXXX");

parms.Add(RfcConfigParameters.Client, "200");

parms.Add(RfcConfigParameters.Language, "EN");

parms.Add(RfcConfigParameters.PoolSize, "10");

Using the above parameters it working. But I don't want to go with User credentials. It should authenticate with a User ID. Like below parameters .

parms.Add(RfcConfigParameters.MessageServerHost, "EAYQSAPXXX");

parms.Add(RfcConfigParameters.LogonGroup, "SUPPORT");

parms.Add(RfcConfigParameters.SystemID, "QEX");

parms.Add(RfcConfigParameters.User, _userEmpId);

parms.Add(RfcConfigParameters.Password, string.Empty);

parms.Add(RfcConfigParameters.Client, "200");

parms.Add(RfcConfigParameters.Language, "EN");

parms.Add(RfcConfigParameters.PoolSize, "10");

parms.Add(RfcConfigParameters.SncMode, "1");

parms.Add(RfcConfigParameters.SncMyName, "p:CN=QG785XZ@US.NA.EY.NET");

parms.Add(RfcConfigParameters.SncPartnerName, "p:CN=SAP/KerberosQE2@EY.NET");

Can you please provide a code example in ASP.net WEB API C# ??

Instead of username and password, a Kerberos ticket can be used. I am unable to share any code on here, sorry.
