• What is the cause and solution for SAP error message CB456 - Selection is restricted to & entries ?

  The SAP error message CB456 ("Selection is restricted to & entries") typically occurs when a user attempts to execute a report or transaction that retrieves a large number of entries, exceeding the system's predefined limit for selection. This limit is often set to prevent performance issues or excessive resource consumption.
  Cause:
  
  Exceeding Entry Limit: The error is triggered when the number of entries returned by a selection exceeds the maximum allowed limit set in the system.
  System Configuration: The limit is often configured in the system settings, which can vary based on the specific SAP environment and the transaction being executed.
  Performance Considerations: SAP systems impose these limits to ensure that queries do not overload the system and to maintain performance.
  
  Solution:
  
  
  Refine Selection Criteria: Modify the selection criteria to narrow down the results. This can include:
  
  Adding more specific filters.
  Using date ranges or other parameters to limit the data set.
  
  
  
  Check System Settings: If you have the necessary authorizations, you can check the system settings for the maximum number of entries allowed. This can be done in transaction codes like SE38 or SE80 to look at the program or report settings.
  
  
  Use Pagination: If the report supports it, consider using pagination or batch processing to retrieve data in smaller chunks.
  
  
  Consult with Basis Team: If you believe the limit needs to be adjusted, consult with your SAP Basis team. They can modify the system settings if appropriate, but this should be done with caution to avoid performance degradation.
  
  
  Review Documentation: Check SAP Notes or documentation related to the specific transaction or report for any known issues or recommendations.
