• What is the cause and solution for SAP error message /SAPAPO/MAT231 - Too many objects were selected ?

  The SAP error message /SAPAPO/MAT231 Too many objects were selected typically occurs in the context of SAP Advanced Planning and Optimization (APO) when a user attempts to select or process a large number of objects (such as materials, orders, or other entities) in a single operation. This error is a safeguard to prevent performance issues or system overloads that can arise from processing too many objects at once.
  Cause:
  
  Exceeding Limits: The system has predefined limits on the number of objects that can be processed in a single transaction. When this limit is exceeded, the error is triggered.
  Performance Considerations: The error is designed to protect the system from performance degradation that could occur if too many objects are processed simultaneously.
  User Selection: The user may have inadvertently selected too many items in a list or report.
  
  Solution:
  
  Reduce Selection: Try to limit the number of objects you are selecting. Instead of selecting all items, filter your selection criteria to reduce the number of objects to a manageable amount.
  Batch Processing: If you need to process a large number of objects, consider breaking them down into smaller batches. Process each batch separately to avoid hitting the limit.
  Check System Settings: Consult with your SAP Basis or system administrator to check if the limits can be adjusted in the system settings, although this is generally not recommended due to potential performance impacts.
  Use Alternative Transactions: If applicable, use different transactions or reports that are designed to handle larger selections more efficiently.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or updates regarding this error message.
