Have you ever wondered how to communicate SAP and PI System?
OSIsoft has developed the SAP HANA IoT Integrator by OSIsoft. This integrator works unidirectionally from PI to SAP Hana.
How would be possible to get data from SAP then?
SAP has a connection platform called SAP Plant Connectivity (PCo). This platform is able to communicate the SAP modules to external devices through known protocols such OPC, OLEDB and ODBC.
This documentation documentation shows more information about SAP Plant Connectivity.
It is also possible to use Scheduled Jobs to generate and read text files.
