Hello,
I'm trying to create some odata services with the option to subscribe to collections and receiving notifications via pull (NOTIFICATIONSTORE) on Netweaver Gateway 2.0sp6.
I've read a lot of documentation about this lately(e.g.:
)
which seem to be obsolete or just refer to a push scenario.
What works is the first one(1) which gave mit the first success moment(I get notified when a user gets created, changed or deleted 
).
Furthermore I changed that example a little to fit to a subscription to the MaterialCollection in my example odata service.
So after creating an own implementation of "BI_EVENT_HANDLER_STATIC" and using it as the rfc endpoint for my event, I also get notifications when a material gets created.
But in the standard documentation there is allways being referred to the /IWBEP/BOR_ADAPTER as the endpoint for the event.
After a lot of debugging I found out, that the subscriptions made to my collection are not being used as a subscription to the corespinding event.
I think because of missing or wrong GSDO configuration. But I'm clueless here.
What configuration has to be done, so that if someone subscribes to an odata channel, he gets a notification when the coresponding backend events are thrown?

Just says "Configured a GSDO group in SAP NetWeaver Gateway for the application that starts the backend event subscription" but I did not find out how to do so.
The point "Manage GSDO Group for OData Service" mentioned here http://help.sap.com/saphelp_gateway20sp06/helpdata/en/70/be3b976c614b4f92f1fe75b2fd0ab7/frameset.htm just does not exist in our system.
Any clues or resources etc. how to continue on that topic?
Thanks.
