The RFC connection between SAP Business Information Warehouse (SAP BW) and SAP ERP (1) is required for the report-report interface.
In the figure, Knowledge Provider (KPro) is installed on the same instance as SAP ERP. You can also install KPro on an external content server and connect it using RFC or HTTP(S).
If you want to use the product SAP Talent Visualization by Nakisa
(“Nakisa Server”), you need to purchase your own license for this.
