Mix of SAP Gateway and non SAP Gateway for Integration with SAP
I am looking for a document on where SAP NW Gateway fits in as part of an integration overall strategy. So, for example, my understanding it is primarily for Mobile app integration. I hear some customers talking about using Gateway for what we normally think of as EAI core integration. So, it does not seem right to me in many typical SAP integration requirements would be handled via Gateway. Other traditional SAP integrations via PI or another ESB leveraging enterprise services, SAP API like BAPIs and IDOCS would be more appropriate in many non-mobile type situations.
Does anyone have general guidance on the above integration advice, thx
