SSO configuration for SAP BO SP6 on Sharepoint 2013 on premise

I have SAP BO SP6 installed on SharePoint 2013 on premise server. I have configured a completely seperate web application on SharePoint 2013 on premise. I have followed the instructions found below to configure the SSO within Web.configs:

I have also confirmed using the Event Viewer and klist command that the webapplication is enabled for kerberos authentication

I have also done IIS configuration to enable SSO

Still no luck. Any experts out there who has configured this?

Thanks
