• What is the cause and solution for SAP error message CI421 - Please limit selection ?

  The SAP error message CI421 ("Please limit selection") typically occurs when a user attempts to execute a report or transaction that retrieves too many records or data entries, exceeding the system's limits for processing or displaying data. This can happen in various contexts, such as when running reports, queries, or data extraction processes.
  Cause:
  
  Excessive Data Volume: The selection criteria used in the report or transaction may be too broad, resulting in a large number of records being selected.
  System Limitations: SAP has built-in limits to prevent performance issues, and if the selection exceeds these limits, the error is triggered.
  Configuration Settings: Certain settings in the SAP system may restrict the number of records that can be processed or displayed at one time.
  
  Solution:
  
  
  Refine Selection Criteria: Narrow down the selection criteria to limit the number of records being retrieved. This can include:
  
  Adding more specific filters (e.g., date ranges, specific document types, or status).
  Using additional selection fields to reduce the dataset.
  
  
  
  Use Pagination: If the report or transaction supports it, consider using pagination or batch processing to retrieve data in smaller chunks.
  
  
  Check System Settings: Consult with your SAP Basis or system administrator to review any configuration settings that may be affecting data retrieval limits.
  
  
  Run in Background: If applicable, try running the report in the background, which may allow for larger data sets to be processed without hitting the interactive limits.
  
  
  Consult Documentation: Review the specific documentation for the transaction or report you are using, as there may be recommendations for optimal selection criteria.
  
  
  Contact Support: If the issue persists, consider reaching out to your SAP support team for further assistance, as they may have insights into system-specific configurations or limitations.
