On running Discoverer report for Gully asset types against the network, a user is getting the error message
ORA-20002: HIG-0067: Record not found: nm_elements_all (NE_PK) ne_id =>
ORA-06512: at "HIGHWAYS.HIG", line 1464
ORA-06512: at "HIGHWAYS.NM3GET", line 4781

Check whether the particular Asset type is tied to the network or not.
Open the Asset Metamodel form (NM0410), go to the Network tab and if there is no netwok type listed that is why asset type is not being displayed in Discoverer report. The report will need either to list assets without the network location, or locations will need to be added for the assets.
