Hi guys, I'm new to Portal administration.
I have a Portal version 7.4 with backend ERP 6.0 EHP7 . The ESS application is configured.
Today the Portal server was restarted (only Portal - Not ERP), and then in the ESS application when the actions for travel requests save the system displays this error:
"Sorry, a connection problem occurred. Error Typed model execution failed, see nested exception for details"
When I check the logs of the portals I find these errors:
com.sap.netweaver.bc.uwl.core.push.NotificationRegistrationManager
Location: Single Click Filter by Location Negative Single Click Filter by Location com.sap.netweaver.bc.uwl.core.push.NotificationRegistrationManager

Hi Desiree,
Have you checked the Destinations in NetWeaver Administrator (NWA -> Configuration -> Security (or Infrastructure) -> Destinations)? Specifically, check WD_MODELDATA_DEST, and that the Authentication for this Destination is set to Current User (Assertion Ticket) (WD_RFC_METADATA_DEST, on the other hand, should be Technical User).
The other place to check backend connections is from the Portal interface, via System Administration -> System Landscape.
Cheers,
