What are the available Nintex connectors to connect SharePoint Nintex workflow with SAP ERP Data?. During the demonstration of the Nintex product they have shown us the connectivity between SAP ERP with Nintex but now we are not able to find any connector for matching for ERP.

I did search bit in the Internet, It seems we are required to purchases additional licenses for Theobald ERP Connect Solution. Could you clarify what are the options we have now?
