Previous Day Assignment in Pair Formation 
Purpose
At the start of pair formation, the individual time events are assigned to a specific day. This can be the current or the previous day, according to the employee’s daily work schedule.

A time event can never be assigned to a subsequent day in pair formation.

Previous day assignment:
Planned working time (DWS) |
01/02/1996 |
22:00 – 06:00 |
Clock-in entry |
01/02/1996 |
21:56 |
Clock-out entry |
01/03/1996 |
06:07 |
Time pair |
01/02/1996 |
21:56 -30:07 |
The employee has worked a night shift. In order that pair formation can be carried out, the clock-out entry must be assigned to the previous day. This is done by comparing the time events to the relevant daily work schedule.
Process Flow

Evaluating the interval between time events:
Planned working time (DWS) |
01/02/1997 |
06:00 – 14:00 |
Clock-in entry |
01/02/1997 |
05:56 |
Clock-out entry |
01/03/1997 |
14:03 |
By consulting the daily work schedule, the system is able to ascertain that the time span between the two time events is too great for a realistic pair to be formed. The second time event is therefore not assigned to the previous day.
The following open time pairs are formed:
Pair formation: |
01/02/1997 |
05:56 – ____ |
|
01/03/1997 |
____ -14:03 |
The system specifies a message for the open time pairs using the status from pair formation (STAT1):
