The technical settings of a table define how the table will be handled when it is created in the database, that is whether the table will be buffered and whether changes to data records of the table will be logged.

The most important parameters are:

Data class: The data class defines the physical area of the database (tablespace) in which the table should be created.

Size category: The size category defines the size of the extents created for the table.

When the table is created in the database, the required information about the memory area to be selected and the extent size is determined from the technical settings.

Buffering permission: The buffering permission defines whether the table may be buffered.

Buffering type: If the table may be buffered, you must define a buffering type (full, single-record, generic). The buffering type defines how many table records are loaded into the buffer when a table entry is accessed.

Logging: This parameter defines whether changes to the table entries should be logged. If logging is switched on, each change to a table record is recorded in a log table.

The Convert to transparent table flag ( transparent flag) is also displayed for pooled tables or for tables which were converted into transparent tables earlier on with this flag.

Hi,

Technical Settings: The technical settings control, for example, table buffering.

Select Data Class (Mandatory) [APPL0]

Select Size Category (Table size - No. of records - Mandatory) [1 to 6]

Specify Buffering [allowed / not allowed]

Save

Check Inconsistencies

Activate & Go Back to “Maintain Table Screen”

Data Class: 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

Size category: The size category determines the probable space requirement for a table in the database.

Buffering: The buffering status specifies whether or not a table may be buffered.

Regards

Nicole

In technical settings we can specify the data class , size category, buffering is needed or not etc.

data class :

In data class we can give the type of the table we are creating(for eg; master table, transaction table, organization table etc.

size category:

shows how many data records correspond to the individual categories

hi srinath,

The technical settings are used to individually optimize the storage requirements and accessing behavior of database tables.

The technical settings can be used to define how the table should be handled when it is created on the database, whether the table should be buffered, and whether changes to entries should be logged.

The table is automatically created on the database when it is activated in the ABAP Dictionary. The storage area to be selected (tablespace) and space allocation settings are determined from the settings for the data class and size category.

The settings for buffering define whether and how the table should be buffered.

If u still much more details, revert back to me.
