Overview & Features in HR Programming
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.
Infotypes mirror a quantity of connected data
records; infotypes are identifiable through a four
character numerical string [e.g. infotype Addresses
(0006)] and a complete listing is included.
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 infotype
records. Infotypes can be processed individually or
in fast entry mode.
Difference from conventional ABAP
Advanced Business Application Programming ABAP
is SAP's fourth generation language. All of R/3's
applications and even parts of its basic system are
developed in ABAP. ABAP is used for customization
and modification of SAP applications.
In HR ABAP use of select statements significantly
less than in other areas of ABAP development,
Logical databases have limited applications in other
modules but are very useful in HR. Also, you really
need to understand the infotype time constraint
concept, 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. Worst-case scenario,
use a select statement.
