Table Category of Database Tables

Other versions: 7.31 | 7.40 | 7.54

Transparent tables

The default table category is the transparent table. In transparent tables, the database object has an identically named variant with the same columns as in the definition in ABAP Dictionary. The fields of transparent tables can be edited using Native SQL or AMDP as well as using ABAP SQL. Outside AS ABAP, they can be edited using the programming interface of the database. The latter method is, however, not recommended.

Global temporary tables

Global temporary tables are a further category of table. A global temporary table (GTT) is a special transparent table used exclusively as a repository of temporary data during a database LUW.


The ABAP Dictionary tool makes it possible to transform database tables from one category to another. To create a different table category as a transparent table, a transparent table must be created first and then transformed into a different table category. In Dictionary DDL, the table category is defined using the annotation @AbapCatalog.tableCategory.
