External Supply of the Time Sheet 
Use
If you implement an external application for time recording in your enterprise, you can use it to supply the
SAP Time Sheet with external time data. In addition, you can use your external application to display a Time Sheet
worklist for each personnel number or time sheet data.A standardized interface is available for this purpose.

Prerequisites
You use the Time Sheet to record and process durations in hours; your external application must therefore also make working times available as a number of hours. Clock-in and clock-out entries alone cannot be processed in the Time Sheet.
Features
You can use the interface for supplying the Time Sheet with external data to fill all the fields that you have set up in the Time Sheet.
You can make data available to the following SAP components:
If you implement SAP Human Resources, you can make the master data created there available for checking using the external application. You can transfer the master data in two ways:
A delta download providing the external system with master data takes place in this version of data transfer. The Interface Toolbox enables you to store master data in files that match the table structure of the external system. In this way, the tables of the external systems do not have to be modified to match the structures.
IDoc.
In this version of data transfer, all HR master data is replicated. In the external system, the applicable tables must be modified to match the structures of the IDocs. In addition, you must maintain the
ALE Distribution Model as required.
