]po[ Hour

A "timesheet hour" represents the work done by an employee at a certain project. Actually, timesheet hours are not a real ]project-open[ objects because they does not reference the acs_objects table and don't support services such as permissions. 

Fields of the im_hours Table:

• User (user_id:integer references users):
  The user who has logged some hours.
  
• Project (project_id:integer references im_projects):
  The project or timesheet task on which the hours have been logged.
  
• Day (day:timestamptz):
  The day when the hours have been logged.
  
• Hours (hours:numeric)
  The number of hours logged
• Billing Rate (billing_rate:numeric):
  Not used currently. May be deleted in one of the next versions.
• Billing Currency (billing_currency:char(3)):
  Not used currently. May be deleted in one of the next versions.
• Note (note:text):
  Comment on what has been done during the time logged.
  
• Timesheet Task2 (timesheet_task2_id:integer)
  Not used currently. May be deleted in one of the next versions. 
• Confirmation Object (conf_object_id:integer references im_timesheet_conf_objects):
  A reference to a confirmation object. This conf objects represents a confirmation request, when a user clicks on the button "submit hours for configuration" in the timesheet GUI. The confirmation object contains a conf_status_id that can be Requested, Active or Rejected. This way you can distinguish between confirmed timesheet hours and unconfirmed hours.
  
• Timesheet Cost (cost_id:integer references im_costs):
  Reference to the cost item with the financial impact of the logged hours.
  When logging hours, ]po[ will automatically create a financial item of type "Timesheet Costs" to represent the cost of hours. The amount of the timesheet cost item is calculated as number of hours x hourly cost (im_employees.hourly_cost of the user logging the hours).
  
• Timesheet Invoice (invoice_id:integer references im_costs):
  Link to a Timesheet Invoice containing the logged hour. This way we can keep track of non-billed hours delivered to a customer. Please see the Timesheet Invoices for detailes on Timesheet billing.
  
• Material (material_id:integer references im_materials):
  ]po[ allows to specify the material (type of service) when logging hours. This way, a user logging hours can differentiate between the type of services delivering. You need to enable the parameter [HourLoggingWithMaterialsP] in order to use this feature. In that case. ]po[ will show a drop down field with materials for every hour logged.
  
• Internal Note (internal_note:text):
  Allows a user to differentiate between "internal" and "external" comments about what the user has done if the parameter [HourLoggingInternalCommentP] is enabled. The "internal" comment is used if the external comment will be presented directly to a customer.
