SAP Error Message - Details

• Message type: E = Error

• Message class: NRSCNV - Message class

• Message number: 267

• Message text: Performance can be increased by deactivating table backups

What causes this issue?

The framework has detected that you only added operations of a deletion
type (such as "delete characteristic", "delete key figure", "delete
dimension"), type "add characteristic" with filling method constant or
type "add key figure" with filling method constant. In addition, the
framework is configured to make a backup of all affected tables.

System Response

Since only characteristics or key figures will be deleted<(>,<)> you can
increase the remodeling performance significantly by switching off the
backup feature for all affected tables.
<ZH>NOTE: </>switching off backups for all affected tables means that
you cannot reset or restart the conversion if an error occurs. To
minimize the risk of errors<(>,<)> try executing the conversion in a
safe environment (a development or quality system with test data).

How to fix this error?

To switch off the table backup function, open the configuration screen
and deselect the <ZK>Always Make Backup Of Tables </>checkbox.

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 NRSCNV267 - Performance can be increased by deactivating table backups ?

  The SAP error message NRSCNV267 indicates that the performance of a data conversion or migration process can be improved by deactivating table backups. This message typically arises during data migration or conversion activities, particularly when using tools like the SAP Data Migration Cockpit or similar utilities.
  Cause:
  The primary cause of this error message is that the system is performing backups of the tables involved in the data migration process. While backups are essential for data integrity and recovery, they can significantly slow down the performance of the migration process, especially when dealing with large datasets. The system is suggesting that by disabling these backups, the performance of the migration can be enhanced.
  Solution:
  To resolve this issue and improve performance, you can consider the following steps:
  
  
  Evaluate the Need for Backups: Before deactivating table backups, assess whether it is necessary to have backups during the migration process. If the data is already backed up or if the migration is being performed in a controlled environment, you may choose to disable backups.
  
  
  Deactivate Table Backups:
  
  If you decide to proceed, you can deactivate the table backups in the migration tool or process you are using. This is usually done in the settings or configuration options of the migration tool.
  Look for options related to "Backup" or "Data Protection" and set them to "Off" or "Deactivate".
  
  
  
  Monitor Performance: After deactivating backups, monitor the performance of the migration process. Ensure that the process runs smoothly and that there are no data integrity issues.
  
  
  Re-enable Backups Post-Migration: Once the migration is complete, it is advisable to re-enable table backups to ensure data safety and integrity for future operations.
  
  
  Related Information:
  
  Data Migration Best Practices: Always ensure that you have a reliable backup strategy in place before performing any data migration. This includes having a full backup of the database and understanding the rollback procedures in case of failure.
  Performance Tuning: Besides deactivating backups, consider other performance tuning measures such as optimizing the database, increasing system resources, or running the migration during off-peak hours.
  SAP Notes and Documentation: Check SAP Notes and official documentation for any specific recommendations or updates related to the NRSCNV267 message and the migration tools you are using.
  
  By following these steps, you should be able to address the NRSCNV267 error message and improve the performance of your data migration or conversion process.
