I want to query data from a report in SSRS 2019 Standard in Excel by using data feed.
As described in
Generate Data Feeds from a Report (Report Builder and SSRS), I exported the data feed service document:

But when I open the service document xxx.atomsvc, there is no such an URL with the format described in the documentation of Microsoft:
https://<server name>/ReportServer?%2f<ReportName>rs%3aCommand=Render&rs%3aFormat=ATOM&rc%3aDataFeed=<Identifier>
Instead, the URL looks like
http://<servername>/ReportServer?%2F<Report>&rs%3ACommand=Render&rs%3AFormat=ATOM&rc%3AItemPath=<tablename>"
How do I get the <Identifier> to use the URL format provided for Microsoft, where can I find or configure it?
Appreciate any answers!
Thanks, Andreas
P.S. Sorry for the obviously wrong choice for the forum, but I was not able to make a choice in the list of available forums which makes any sense. There is no SSRS forum, either no SQL Server forum.
