Role wise user access

Dear All,

We have deployed ByD solution in our company, but in initial phase we didn't use to user roles.

here im looking for user specific access to business center (BC) & work centers (WC)

for e.g.

Account Executive Access :

1. Payment Management (BC)

• Payment Monitor (WC)
• Payment Allocation (WC)
• Petty Cash (WC)
• Deposits (WC)

   2. General Ledger (BC)

• General Ledger Accounts (WC)
• General Entry  (WC)

Account Manager Access :

1. General Ledger (BC)
   • Master Data
   • Closing Cockpit
   • Periodic Task

such i want to define all roles given in system.

Thank you.
