[Former Member]

Hi.

I need to know what is "data class". I am aplying a hot package in SAP, and it generated a error because el data class USR34 not exists associated with cdhdr table. The note says that I must create it, but I don´t know how I must to do it.

And I don't know if I can associate other data class that exists as USR33.

Thanks for your help.

Hello Maria,

Data class is a technical attribute of a table.

Data class in technical settings

    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):

    o   APPL0    Master data

    o   APPL1    Transaction data

    o   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.

Data Class

If you choose the data class correctly, your table is automatically assigned to the correct area (tablespace or DBspace) of the database when it is created. Each data class corresponds to a physical area in which all the tables assigned to this data class are stored. There are the following data classes:

APPL0 (master data): Data which is seldomly changed. An example of master data is the data contained in an address file, such as the name, address and telephone number.

APPL1 (transaction data): Data that is frequently changed. An example of transaction data is the goods in a warehouse, which change after each purchase order.

APPL2 (organizational data): Customizing data that is defined when the system is installed and seldomly changed. An example is the table with country codes.
