User cannot view costing data in MM03/MD04

A user who used to have access to view the costing field in MM03/MD04 has lost the ability to display this data due to a role removal during a 'role consolidation' project. He still has access to the transactions just not the costing field he needs to perform his job. Does anyone know of a quick fix for this? I'm fairly new in my position as a Business Analyst for Production Planning and would appreciate any help with this.
