To answer this question, you need to understand the concept of table buffering in SAP systems.
Table buffering is a technique used to improve the performance of database access in SAP systems. It involves storing frequently accessed database tables in the application server's memory, reducing the need for repeated database queries. However, not all types of tables can be buffered.
Let's go through each option to understand why it is correct or incorrect:
Option A) Transparent table - This option is incorrect because transparent tables can be buffered. Transparent tables are regular database tables in SAP that store data directly without any additional processing.
Option B) Pooled table - This option is incorrect because pooled tables can be buffered. Pooled tables are used to store application data that is accessed by multiple users simultaneously.
Option C) Cluster table - This option is correct because cluster tables cannot be buffered. Cluster tables are used to store large volumes of data in a compressed format, which makes them unsuitable for buffering.
Option D) Internal table - This option is incorrect because internal tables are not stored in the database, so buffering does not apply to them.
The correct answer is C) Cluster table. This option is correct because cluster tables cannot be buffered due to their specific storage format.
