• What is the cause and solution for SAP error message GP521 - The last internal number has been assigned for this activity ?

  The SAP error message GP521, which states "The last internal number has been assigned for this activity," typically occurs in the context of SAP's Project System (PS) or related modules when you are trying to create or assign a new internal number for an activity, but the system has reached the limit of available internal numbers for that particular activity.
  Cause:
  
  Exhaustion of Number Range: The internal number range defined for the activity has been exhausted. This can happen if the number range is not properly configured or if it has been set to a limited range.
  Configuration Issues: The number range settings in the configuration may not allow for sufficient numbers to be generated for the activities.
  System Settings: The system may have been set up to use a specific number range that has been fully utilized.
  
  Solution:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects).
  Look for the relevant number range object associated with the activity (e.g., COSS for cost elements).
  Check the current status of the number range and see if it has been exhausted.
  
  
  
  Extend the Number Range:
  
  If the number range is exhausted, you can extend it by adjusting the upper limit of the number range.
  This can be done in the same SNRO transaction by editing the number range intervals.
  
  
  
  Create a New Number Range:
  
  If necessary, you can create a new number range object to accommodate additional activities.
  Ensure that the new number range is properly assigned to the relevant configuration settings.
  
  
  
  Consult with Basis or Configuration Team:
  
  If you do not have the necessary permissions to change number ranges, consult with your SAP Basis or configuration team to make the required adjustments.
  
  
  
  Check for Custom Developments:
  
  If there are any custom developments or enhancements in your SAP system that might affect number generation, review those as well.
