Have you checked Note 1906173 and Note 1941751? The latter one names a report. You should execute that one. However, it seems the name of it is wrong. It should be: EQ_RS_AUTOSETUP (no guarantee on this one). This should generate the service in the backend.
Afterwards you need to release the service. You need to go to the gateway maintenance service /IWFND/MAINT_SERVICE and add your query as service there. Note that the query name is attached with a _SRV.
