• What is the cause and solution for SAP error message /STMC/CR_MSG806 - Area becomes too large, resizing is not possible ?

  The SAP error message /STMC/CR_MSG806 Area becomes too large, resizing is not possible typically occurs in the context of SAP's data management, particularly when dealing with the resizing of internal tables or memory areas. This error indicates that the area you are trying to resize has exceeded the maximum allowable size, and therefore, the system cannot accommodate the requested change.
  Causes:
  
  Exceeding Memory Limits: The area you are trying to resize has reached its maximum limit, which can happen if the data being processed is too large.
  Inefficient Data Handling: The way data is being handled in the program may lead to excessive memory usage, such as loading too many records into memory at once.
  Configuration Issues: There may be configuration settings in the SAP system that limit the size of internal tables or memory areas.
  Data Volume: High data volume in the database or during processing can lead to this error, especially in batch processing or large report generation.
  
  Solutions:
  
  
  Optimize Data Processing:
  
  Review the program logic to ensure that data is being processed efficiently. Consider using pagination or processing data in smaller chunks instead of loading everything into memory at once.
  Use selection criteria to limit the amount of data being processed.
  
  
  
  Increase Memory Limits:
  
  If applicable, check the system parameters related to memory allocation and increase them if necessary. This may involve adjusting settings in the SAP kernel or database configuration.
  
  
  
  Check for Data Volume:
  
  Analyze the data volume being processed. If the volume is inherently large, consider breaking down the processing into smaller, manageable parts.
  
  
  
  Review Custom Code:
  
  If the error occurs in custom ABAP programs, review the code for any inefficiencies or unnecessary data loads. Use appropriate data structures and avoid using large internal tables when possible.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide guidance on handling large data sets.
  
  
  
  System Monitoring:
  
  Monitor system performance and memory usage to identify any bottlenecks or areas where memory is being consumed excessively.
  
  
  
  Related Information:
  
  SAP Documentation: Refer to SAP's official documentation for guidelines on memory management and best practices for handling large data sets.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have implemented.
  Performance Tuning: Consider performance tuning techniques for your SAP system to improve overall efficiency and reduce memory consumption.
