SMP Integration Gateway / SAP Gateway
i read some documentation and take some webinars to answer the following question: "Do i need an extra SAP Gateway System when i use the SMP with the Integration Gateway to publish SAP Backend ODATA Services?" But i could not find the answer...
My understanding ist that the Integration Gateway of SMP allows to publish ODATA Services by ODC (OData Channel). SAP Backend Systems at least Version 7.42 ingterates the SAP_GWFND component. With this Component iam able to develop ODATA Services (MPC / DPC) at the Backend Site. Normally i publish this Services to SAP Gateway. Is it also possible to publish the Services to SMP Integration Gateway?
Regarding your question:
"Do i need an extra SAP Gateway System when i use the SMP with the Integration Gateway to publish SAP Backend ODATA Services?"
The answer is no.
The SAP Integration Gateway is a component from the SAP Mobile platform that provides the ability to enable Odata services from various SAP and non-SAP (OData and non-OData) datasources.
