Limiting user edit access to column in a module?
I am trying to create a DCA to control access to editing 2 columns in a module by specific user. The modules are accessible by 2 roles (Planners & Category Managers). Currently both roles have write access to the module. However I want to restrict the Category Managers to be able to edit only 2 columns in the module.(L2 Taxonomy & L3 Taxonomy. Both column are list formated) .Any idea how to go about it?
