ESS for end user: Error Typed model execution failed, see nested exception for details

[former_member287614]

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:

I´m check the connection for JCOs and UWL is OK.

I do not know what to check.

I appreciate any help

regards.

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,
Matt

Hello Matt thanks for the replay.

I´m check both connection is ok:

RFC Destination ZWD_GV_MODELDATA_DEST /ZWD_GV_RFC_METADATA_DEST:

Successfully connected to system <sid> as user J2EE_ADMIN
Successfully connected to system <sid> as user SAPJSF

regards

[Matt_Fraser]

Hi Desiree,

Ok, I guess your destinations are copies of the standard destinations WD_MODELDATA_DEST and WD_RFC_METADATA_DEST. So, you have ZWD_GV_MODELDATA_DEST connecting as J2EE_ADMIN? I think this is probably incorrect. Instead the MODELDATA connection should use Current User (Assertion Ticket) as the authentication method.

The METADATA connection should use Technical User and logon as SAPJSF, so that part's correct.

Cheers,
Matt

Hi Matt.

Thanks for replay.

We find the errors and are functional product of a number conversion when recording a travel request. An abap consultant is already checking.

Thanks for help me

I´m close this message
