How To Fix DT748 - Table & is participating in DataAging; therefore buffering not possible

SAP Error Message - Details

• Message type: E = Error

• Message class: DT - Table activation (incl. indexes)

• Message number: 748

• Message text: Table & is participating in DataAging; therefore buffering not possible

What causes this issue?

This table takes part in DataAging. This means that its data is managed
on the database as current ("hot data") and less current ("cold data").
No buffering can be activated for such tables because in the table
buffer no corresponding administration is implemented.
A special table column with the name _DATA_TEMPERATURE indicates that
the table is participating in DataAging.

System Response

The table is not activated.

How to fix this error?

If the table is to take part in DataAging, buffering must be switched
off. Otherwise, the temperature column must be removed.

Procedure for System Administrators

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

• What is the cause and solution for SAP error message DT748 - Table & is participating in DataAging; therefore buffering not possible ?

  The SAP error message DT748 indicates that a specific table is participating in Data Aging, which means that the table is configured to manage data lifecycle and retention. As a result, buffering for that table is not possible. This is a common scenario in systems that implement data aging to optimize performance and manage data more effectively.
  Cause:
  
  Data Aging Configuration: The table in question is part of the Data Aging framework, which is designed to handle large volumes of data by archiving or deleting older data that is no longer needed for day-to-day operations.
  Buffering Restrictions: When a table is configured for Data Aging, it typically cannot be buffered because the data in the table may change frequently as data is aged out or archived, making it unsuitable for caching.
  
  Solution:
  
  Review Data Aging Settings: Check the configuration of the Data Aging settings for the table. If buffering is necessary for performance reasons, consider whether the table should be removed from the Data Aging configuration.
  Adjust Buffering Strategy: If the table must remain in the Data Aging framework, you may need to adjust your overall buffering strategy. This could involve optimizing other tables that are not part of Data Aging or using different performance tuning techniques.
  Consult Documentation: Refer to SAP documentation regarding Data Aging and buffering to understand the implications of these settings and how they can be managed.
  Performance Monitoring: Monitor the performance of your system to determine if the lack of buffering on this table is causing significant performance issues. If so, consider alternative approaches to manage data access and performance.

  Data Aging: This is a feature in SAP that allows organizations to manage the lifecycle of their data, ensuring that only relevant data is kept in the active database while older data is archived or deleted.
  Buffering in SAP: Buffering is a performance optimization technique that allows frequently accessed data to be stored in memory, reducing the need to read from the database repeatedly.
  SAP Notes and Documentation: Check SAP Notes for any specific guidance or updates related to the DT748 error message and Data Aging. SAP's official documentation can provide insights into best practices for managing Data Aging and buffering.
