Extended Checks for Users of HR Time Management
Use
If you implement HR Time Management, there are extended checks available when you enter time sheet data. They allow you to validate the data entered against target hours and attendance/absence quotas, and to check for collisions with existing SAP Human Resources data.
Features
Validating the Data Against Target Hours
The target hours can be taken from the specifications in the employee’s personal work schedule or from the results of time evaluation (time type 0050 - productive hours, for example).
When you maintain your profiles, you can define upper and lower tolerances. The system then checks that the attendance times entered observe these tolerances.
When you set up a profile, note that the system cannot take account of attendance quotas (for overtime, for example) when checking that tolerances have been observed. It cannot be guaranteed that the correct amount of time would be deducted from the quotas.
The system checks the tolerances for all released data in the current data entry period whenever you perform an
action that merits a check.When you save or check the data, the system additionally validates all data within the data entry period.
To simplify data entry, the system only checks for a deficit in target hours when you save or check data, and only up to the current system date. It always checks that the target hours have not been exceeded, however.
Validating Data Against Quotas
If an attendance or absence type is deducted from a quota, the system can check whether sufficient quota is available as soon as data is entered in the time sheet. The system takes account of the quotas for the Attendance Quotas (2007), Absence Quotas (2006), and Leave Entitlement (0005) infotypes.
All data within the data entry period is checked, since a new or changed entry can affect quota deduction for existing records.
The system only carries out these comprehensive checks when you:
Checking for Collisions with Attendances and Absences in HR
The system only checks for collisions between new or changed time sheet records and existing HR data records, and only for the current data entry period .
Released records are always checked whenever you perform an action meriting a system check. When you check data, data assigned the status In process is also checked.
