Hi

There won't be any problem

nothing will happen

The data class defines the physical area of the database (for ORACLE the TABLESPACE) in which your table is logically stored. If you choose a data class correctly, your table will automatically be assigned to the correct area when it is created on the database.

The most important data classes are (other than the system data):

APPL0 Master data

APPL1 Transaction data

APPL2 Organizational and customizing data

Master data is data which is frequently read, but rarely updated. Transaction data is data which is frequently updated.Organizational und customizing data is data which is defined when the system is initialized and then rarely changed.

There are two more data classes available, USR and USR1. These are reserved for user developments. The tables assigned to these data classes are stored in a tablespace for user developments.

Hi

APPL0 is for Master data (data frequently accessed but rarely updated).

APPL1 is for Transaction data (data that is changed frequently).

Hi,

The Data class determines in which tablespace the table is stored when it is created in the database. What is a Size Category? The Size category describes the probable space requirement of the table in the database. How Many types of size categories and data classes are there? There are five size categories (0-4) and 11 data classes, only three of which are appropriate for application tables:

- APPL0 - Master data (data frequently accessed but rarely updated)

- APPL1 - Transaction data (data that is changed frequnetly)

- APPL2 - Organisational data (customizing data that is entered when system is

configured and then rarely changed)

so you can't use APPL1 instead APPL0

Hi,

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

· APPL0- 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
