Hi
In so many of blogs i have seen writing the SAP Gateway server (Front end component), SAP Gateway Backend Server ( Backend component + ECC Business Suite). but i am always confused Backend server means it is an ECC system. But later i have understand that by looking at the deployment options. Gateway server itself splitting into two servers as front end and back end server. But i have few questions related to Deployment option1 ( Hub Deployment with Service Development in the SAP Business Suite Back end ) and Deployment option2 (Hub deployment with Service Development in the SAP Gateway Hub).
Here is my following SAP Front End Server(Gateway)
Here is my following SAP Backend Server ( Backend Comp+ SAP ECC)
--------------------------------- Option 1
Having the GW_FND component in both servers, It means that is this called as deployment (( Hub Deployment with Service Development in the SAP Business Suite Back end ))
-----------------------------
What configurations need to be in SAP Front end server & SAP Back end Server to develop the Data Model.
When i develop the service in Back End server and try to register , I am unable to register register giving the error as System alias doesn't exist. But i have created the system alias
If i create the system alias in back end server, do i need to create the system alias for back end server or front end server. Please clarify.
Isn this option, can i able to register the service from the SEGW transaction itself ? or Do i need to register this service by going to SAP Gateway front end server using the /IWFND/MAINT_SERVICE transaction? Please clarify?
------------------------------------------------------------------ Option 2
Hub deployment with Service Development in the SAP Gateway Hub).
-----------------------------------------------------------------------
In case if i want to use the Front end server Gateway hub as both Front end and back end component of Gateway server as Central hub to connect the SAP Business suite.
In this option, What are the configuration need to be done in both systems?
How to create data model in SAP Gateway server with with the data structure exist in back end server.
Thanks
