Core Time Tracking Entities

APP_Timesheet

The central entity for recording working time. Every time entry in time cockpit is a timesheet record.

Purpose: Records individual time entries with begin/end times, project/task assignments, descriptions, and billing information.

Key Properties

Property	Type	Required	Description
`APP_TimesheetUuid`	Guid	PK	Unique identifier
`APP_BeginTime`	DateTime	Yes	Start time of work
`APP_EndTime`	DateTime	Yes	End time of work
`APP_DurationInHours`	Decimal	Calculated	Duration = (EndTime - BeginTime) in hours
`APP_Description`	Text(500)	No	Work description/notes
`APP_DateActual`	Date	Calculated	Date(BeginTime) - used for grouping
`APP_Billable`	Boolean	Yes	Default: true - Is this time billable to customer?
`APP_Billed`	Boolean	Calculated	Has this been assigned to an invoice?
`APP_HourlyRateActual`	Decimal(18,2)	No	Hourly rate at time of booking (from project or user)
`APP_HourlyRateBilled`	Decimal(18,2)	No	Rate actually billed (set when creating invoice)
`APP_Revenue`	Decimal(18,2)	Calculated	`DurationInHours * HourlyRateActual`
`APP_IsDurationTimesheet`	Boolean	Yes	Default: false - Duration only (no specific times)?
`APP_Location`	Text(100)	No	Where the work was performed
`APP_JourneyFrom`	Text(100)	No	Travel: starting point
`APP_JourneyTo`	Text(100)	No	Travel: destination
`APP_JourneyDistance`	Decimal(18,2)	No	Travel distance in km
`APP_IsRunning`	Boolean	No	Is timer currently running?

Relationships

Relation	Target	Cardinality	Required	Description
`APP_UserDetail`	APP_UserDetail	Many-to-One	Yes	Who logged the time
`APP_Project`	APP_Project	Many-to-One	No	Project assigned to
`APP_Task`	APP_Task	Many-to-One	No	Task assigned to (implies project)
`APP_Invoice`	APP_Invoice	Many-to-One	No	Invoice this time was billed on

`APP_JourneyMeansOfTransport`	APP_MeansOfTransport	Many-to-One	No	Travel method (car, train, plane)

Business Rules

Project or Task Required: Either APP_Project or APP_Task must be set
Task Implies Project: When APP_Task is set, APP_Project is derived from Task.Project
Hourly Rate Calculation:
- If APP_Task.HourlyRate is set → use task rate
- Else if APP_Project.HourlyRate is set → use project rate
- Else if APP_Customer.HourlyRate is set → use customer rate
- Else → use user's internal APP_UserDetail.HourlyRate
Billable Calculation: APP_Billable defaults to project/task billable flag
Revenue Calculation: Only calculated if Billable = true and hourly rate is set

Permissions

Read Permission (Row-Level Security):

-- Users can see:
-- 1. Their own timesheets
-- 2. Department leads see their departments
-- 3. Project managers see their projects
-- 4. Billing/HR admins see all

:Iif(
  'BillingAdmin' In Set('CurrentUserRoles') Or
  'HumanResourcesAdmin' In Set('CurrentUserRoles'),
  True,
  :Iif(
    Current.UserDetail.UserDetailUuid = Environment.CurrentUser.UserDetailUuid Or
    ('DepartmentLead' In Set('CurrentUserRoles') And 
     Current.UserDetail.Department In Set('APP_MyDepartmentsAsLead')) Or
    ('ProjectManager' In Set('CurrentUserRoles') And 
     (Current.Project.Manager1 = Environment.CurrentUser.UserDetailUuid Or
      Current.Project.Manager2 = Environment.CurrentUser.UserDetailUuid)),
    True,
    False
  )
) = True

Write Permission:

Users can create/edit/delete their own timesheets
Admins can modify all timesheets
Once billed (APP_Billed = True), only admins can modify

TCQL Examples
