A database table defined in ABAP Dictionary whose database instance is assigned to more than one table defined in ABAP Dictionary. Multiple pooled tables are assigned to a table pool in the database. The key fields of a pooled table have to be character-like fields. The primary key of the table pool consists of two fields: TABNAME for the name of a pooled table and VARKEY for the concatenated content of the key fields of this pooled table. The non-key fields of the pooled tables are compressed and saved in the column VARDATA of the table pool. You can access pooled tables using Open SQL only. Certain other restrictions also apply.
