Connection with External Time Recording
Systems 
This function allows you to upload personnel time events recorded at a time recording system to SAP Time Management (PT). The personnel time events are then processed further in Time Management, so that recorded times can be monetarily valuated at the end of the process in SAP Payroll (PY), ultimately resulting in salary and wages payments for employees.
Time recording systems are connected to Time Management via the Plant Data Collection: Employee Times and Expenditures interface (HR-PDC). HR-PDC is a certified interface, that is, providers of time recording systems can earn certification for their software to communicate with SAP Time Management.
Release 4.5A includes two versions of the interface. The old interface is connected via Communication Channel 1 (CC1).
:
...
1.
Transceiver-Based
Transfer (as of Release 3.0)
2. BAPI-based transfer (as of Release 4.5A)
The following information deals specifically with the version based on BAPI technology.
Via HR-PDC, both personnel time events and employee expenditures (external wage types, cafeteria or service station data) can be uploaded to SAP Time Management.
Two variants of the business process are available:
...
...
a. Clock-in/-out time
b. Clock-in or clock-out entry
c.
Different payment
(in addition to clock-in/clock-out time or clock-in or clock-out
entry)
d. Cost assignment
e. Additional time event types
2. Employee expenditures (can be implemented separately)

The certification process for time recording systems takes place in modules. At least one of the modules detailed here must be certified.
The Customizing steps described in the Personnel Time Events section of the Implementation Guide (IMG) for Personnel Time Management (PT) should be carried out.
The time event types are permitted depend upon the modules implemented in your system, as follows:
