• What is the cause and solution for SAP error message /SAPAPO/SCC124 - Number of objects selected exceeds number of free slots ?

  The SAP error message /SAPAPO/SCC124 Number of objects selected exceeds number of free slots typically occurs in the context of SAP Advanced Planning and Optimization (APO) when the system is trying to process a large number of objects (like orders, stock, etc.) but runs out of available slots in the internal memory or buffer allocated for processing these objects.
  Cause:
  
  Exceeding Capacity: The number of objects being processed exceeds the predefined limit of free slots available in the system.
  Configuration Limits: The system may have configuration settings that limit the number of objects that can be processed simultaneously.
  Memory Issues: Insufficient memory allocation for the APO system can lead to this error.
  Data Volume: Large volumes of data being processed in a single transaction can trigger this error.
  
  Solution:
  
  
  Increase Free Slots:
  
  You can increase the number of free slots available for processing. This can typically be done by adjusting the configuration settings in the APO system.
  Check the relevant configuration parameters in transaction RSCUSTV10 or similar, depending on your system version.
  
  
  
  Batch Processing:
  
  Instead of processing all objects at once, try to break down the processing into smaller batches. This can help to stay within the limits of available slots.
  
  
  
  Memory Allocation:
  
  Review and increase the memory allocation for the APO system if necessary. This may involve adjusting the instance profile parameters in the SAP system.
  
  
  
  Check for Locks:
  
  Ensure that there are no locks on the objects being processed that could be causing the system to think there are fewer slots available.
  
  
  
  System Performance:
  
  Monitor system performance and resource utilization. If the system is under heavy load, consider scheduling the processing during off-peak hours.
  
  
  
  Consult Documentation:
  
  Refer to SAP Notes and documentation for specific guidance related to your version of SAP APO. There may be specific recommendations or patches available.
  
  
  
  Related Information:
  
  SAP Notes: Check for relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.

  Performance Monitoring: Use transaction ST02 (buffer monitoring) and ST04 (database performance) to analyze system performance and identify potential bottlenecks.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP Basis team or SAP support for further assistance.
