Error 'Gateway not connected to local R/3' in Standalone Gateway Gateway trace file(dev_rd)
If ABAP program is running direct on the ASCS instance where the Standalone Gateway is running, generally will get the "Gateway not connected to local R/3" error because On the host there is no R/3 System (Dispatcher and Workprocess) where the Standalone Gateway is running and the gateway could not connect to the local R/3.
1: Please configure Standalone Gateway correctly according to SAP 1010990.
2: Standalone Gateway is designed in such way to handle the programs that act like an RFC-server.
One should need a RFC Destination to an ABAP System to register any program to the gateway.
One should configure the RFC destination to the ABAP system through the HA Gateway as below:
SYSTEM-A > HA GATEWAY > SYSTEM-B(ABAP system)
^^^ ^^^
RFC client RFC server
On the SYSTEM-A side:
Please follow the below steps to configure the RFC destination.
Target system settings: <SYSTEM-B>
Gateway settings: <Standalone Gateway>
If SYSTEM-A is not a ABAP system,
You can find out which program are being directed to the standalone gateway and then try to configure it as above.
