it is a cluster table. Tables which are to be buffered must, however,
betransparent transparent tables or pooled tables.
Probably this error occurred when the table type of a pooled table or
transparent table was changed.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Cancel the buffering type in the technical settings and the buffering
authorization in the table settings. Select <LS>Goto -> Technical

back to cluster and try again to activate the table.

• What is the cause and solution for SAP error message AD934 - Table & is a cluster table. Buffering not allowed ?

  The SAP error message AD934 indicates that you are trying to enable buffering for a cluster table, which is not allowed in SAP. Cluster tables are special types of database tables that store data in a compressed format and are designed to hold related data together. Because of their structure and the way they are used, buffering is not permitted for these tables.
  Cause:
  The error occurs when:
  
  You attempt to enable buffering for a cluster table in the SAP system.
  The system does not allow buffering for cluster tables due to their nature and the way they are designed to handle data.
  
  Solution:
  To resolve this error, you should:
  
  
  Disable Buffering: If you have attempted to enable buffering for a cluster table, you need to disable it. You can do this by going to the table definition in the Data Dictionary (SE11) and ensuring that the buffering option is set to "No buffering."
  
  
  Review Table Design: If you are working with a custom table or modifying an existing one, ensure that you are not trying to apply buffering to a cluster table. If you need to optimize performance, consider other strategies such as indexing or optimizing your queries.
  
  
  Use Alternative Tables: If you require buffering for performance reasons, consider using transparent tables instead of cluster tables. Transparent tables can be buffered, which may help improve performance for certain use cases.
  
  
  Related Information:
  
  Cluster Tables: These are used to store data that is logically related and often accessed together. They are typically used for storing data from multiple tables in a single physical table.
  Buffering in SAP: Buffering is a performance optimization technique that allows frequently accessed data to be stored in memory, reducing database access time. However, it is not applicable to all table types.
  Transaction Codes: You can use transaction codes like SE11 (Data Dictionary) to view and modify table definitions, and SE14 (Database Utility) to manage database objects.
