The Module Matrix is used to give permission to users, roles, groups etc to access the different modules in iTWO cx.
Give Permission to See and Use a Module
1. Navigate to Configure > Modules > Matrix.
2. Against each Module tick or untick the roles you want or don't want to use the module.
For Example: if you tick the SUB role to have access to Contracts Admin, when the SUB logs into iTWO cx they will see Contracts Admin in the Modules in the left pane.
You will need to add the SUB role to the document types in the CA Module that you would like them to be able to access. See here for how to set permissions for document types.
