Hi,
There is no Service Maintenance folder is showing in the tree view in Gateway service builder. As per prerequisites, I had try to maintain systems at below path SPRO ->SAP NetWeaver ->Gateway Service Enablement ->Backend OData Channel ->Connection Settings to SAP NetWeaver Gateway ->SAP NetWeaver Gateway Settings in the Gateway hub system. I failed to found as same as SAP NetWeaver Gateway Settings in the Gateway hub system, but there is something like SAP NetWeaver Gateway Settings. So I have maintained the systems at there.
Even though there is No Service Maintenance folder showing in the tree view in Gateway service builder.
Thanks,
Suresh Yerra.
