Need details on the Duty Roles ending with _OBI, _CRM, _HCM

Summary:

We are creating custom roles for our client. I can see some duty roles ending with _OBI, _HCM, _CRM etc. I want to know the difference between these duty roles.

For example - Receiving Transaction Maintenance has below in the application

ORA_RCV_RECEIVING_TRANSACTION_MAINTENANCE_DUTY, ORA_RCV_RECEIVING_TRANSACTION_MAINTENANCE_DUTY_OBI, ORA_RCV_RECEIVING_TRANSACTION_MAINTENANCE_DUTY_HCM, ORA_RCV_RECEIVING_TRANSACTION_MAINTENANCE_DUTY_CRM
