1. In the field maintenance screen of the table, choose Technical settings.

The maintenance screen of the technical settings appears.

2. Select the data class and size category of the table.

The input help for the Size category field shows how many data records correspond to the individual categories.

3. The buffering permission defines whether the table may be buffered.

If you permitted table buffering, define the buffering type of the table.

You can find further information about when to buffer tables and what buffering type you should choose in Buffering Database Tables.

4. Select Log data changes if you want to log changes to data records of the table (see Logging).

To log changes, system logging must be switched on with the profile parameter rec/client. The Log data changes flag on its own does not cause the table changes to be logged!

5. Choose .

The Convert to transparent table flag is displayed for pooled tables (and tables that were converted to a transparent table with this flag at an earlier time). You can convert the pooled table to a transparent table with this flag (see Converting Pooled Tables to Transparent Tables).

• If the key length of the table is larger than 64, the table cannot be buffered generically.
• If the key length of the table is larger than 120, the table cannot be buffered.
• If the key of the table has more than 86 places or the data part of the table has more than 500 places, it is not possible to log the table.
