SAP HR ABAP Introduction

It is the development of ABAP in the area of HR to meet the clients requirements according to the functional specifications .They may be in any area of HR like in the areas of time aspects ,pay aspects, OM aspects and Self Services like E-recruitment, ESS etc.,

In General Abap,we rarely use logical databases in our programs whilt in HR ABAP, most of the time we are using logical databases to select data from infotypes by using GET event.

the aim in the Human Resources component is to be able to process employee related data according to business requirements in an effective structure. The human Resources module uses a system of data grouped together called infotypes.And storing bulk data like time management and payroll data in cluster files.HR programming involves data extraction and manipulation from these infotypes and clusters using LDB/MACRO and function modules.

Infotype mirror a quantity of connected data records; Infotypes are identifiable through a four character numerical string. You can save the infotypes as time -dependent to enable a retroactive evaluation of employee data. The infotypes appear as an entry screen for the user, through which you can maintain infotypes records.

you really need to understand the info type time constraint concept since the data organization in HR is Employee-Time based,When you cannot get the information that you need out of the logical DB look at the function modules starting with HR and RH.These function modules will provide you with multiple ways of accessing data to save time.
