Error ORA-01400 cannot insert NULL into ukpms_dep_rep_scenarios.udrs_date_created when attempting to create a scenario
The 'who' trigger was missing for this table. To fix this log into SQL*Plus as the Highways owner user and run the exor\nm3\admin\trg\who_trg.sql script. This is often all that is needed for any errors about not being able to insert null into any date created, date modified or created by or modified by field.
