To select an appropriate starter schema for customization, you first need to understand how the functions TIMTP and TYPES work. These functions play an important role in preparing time data for conversion into time wage types and other time results. The time pair plays an integral role in the relationship between the TIMTP and TYPES functions and time data.
Key Concept
TYPES and TIMTP are two examples of a larger set of so-called time evaluation functions. Time schemas use these functions to perform specific tasks. Essentially, a function calls ABAP code that has been designed to perform a certain action. One of the advantages of using predefined functions instead of working directly with ABAP code is that functions, along with their parameters, make it possible to implement time evaluation rules without complex ABAP programming. You are able to customize your schema configuration with functions. Schemas are further customized with personnel calculation rules (PCRs), operations, and their parameters and table configuration.

In my first article of this series (December 2004 issue), I examined a few basic strategies for selecting a time evaluation starter schema. As you become more familiar with time evaluation schemas, it will become clear how these starter schemas are only frameworks for the customized schema you require. As part of the customization process, you will discard some parts of the starter schema and introduce your own custom parts.

In part 2 of the series, I’ll review an integral concept of SAP time evaluation — the time pair. This term refers to a distinct piece of time data that has a duration and frequently a start and end time. I’ll start with the meaning and characteristics of time pairs.

Time Pair Basics

Master data and time data, such as leave requests or work records, form the main data input for the time evaluation program RPTIME00. During processing, this program imports time data with P functions as specified in the time schema. Function P2001 imports absence data, P2002 work data, and P2011 time event data (e.g., clock in and clock out). A few other P functions also import data from a time infotype. For instance, P2000 imports work schedule data from infotype 0007 and P2012 deals with time revision data.
