WHAT IS A SIZE CATEGORY?

The size category describes the probable space requirement
of the table in the database.

WHAT ARE CONTROL TABLES?

The values specified for the size category and data class
are mapped to database –specific values control tables.

**Spoorthi** · 19-03-06, 02:30 PM

HOW MANY TYPES OF SIZE CATEGORIES AND DATA CLASSES ARE
THERE?

There are five size categories (0 – 4) and 11 data clases,
only three of which are appropriate for application tables:

APPLO – Master data (data frequently accessed but rarely
updated)

APPL1- transaction data (data that is changed frequently)

APPL2 – organizational data (customizing data that is
entered when system is configured and then rarely changed)

The other two types are:

USR

USR1 – intended for customer’s own developments
