Demonstrated ability to troubleshoot NAV-specific errors (posting issues, table locks, item ledger entries, dimension conflicts, etc.)
Strong documentation, communication, and stakeholder management skills
Degree in IT, Computer Science, Business Systems, or equivalent practical experience
Experience working on a helpdesk

Nice to have:
