Attendance Quotas Infotype (2007) 
You can use infotype 2007 to enter attendance quotas for employees.
Certain attendances in the HR system may only be used by employees if they have been explicitly assigned attendance quotas with specific time periods for these attendance types.
When you enter an attendance type with quota deduction, the system checks the existing quotas. The attendance record only be stored if sufficient quotas are available. Quotas are updated automatically.
Which attendance types are permissible for an existing quota depends on the Customizing settings.

The attendance quota type Approved overtime is only relevant for time evaluation. Here, the system checks whether the employee’s attendance quota is sufficient.
You can use the Overtime compensation type field to define how overtime is to be deducted and remunerated.
