Resource Manager and Timesheets

Hello Community,

We are testing the possibility of using the Resource Manager and a Timesheet BP in order to control and manage the daily work of the project workforce. The idea is to use the resource manager to define the calendars and capacities of each worker and use the BP to introduce the work performed but in a smart way, by establishing some validations between the capacity defined in the resource and the provided timesheet or by using the defined calendar and not allowing to introduce worked ours in day off dates.

We are facing a lot of design restrictions like non populations, mandatory design requirements or the impossibility to establish some logic on that. Has anyone set up something similar?
