Technical details of SAP transport - SAP newbie!
I am very new to SAP and trying to learn about the possible impacts to our infrastructure. Unfortunately, I have a had a hard time finding substantive documentation other than programming. Does anyone know by what mechanism (layer 4 and above OSI wise) that Netweaver uses to communicate between various landscapes when moving releases through Dev, QA and Prod? What ports does RFC use? Is there any chart that summarizes of this type of network traffic/communication methods in use by SAP?
Any information is appreciated.
