• What is the cause and solution for SAP error message CO081 - External number is not in the number interval (&-&) ?

  The SAP error message CO081, which states "External number is not in the number interval (&-&)," typically occurs when you are trying to create or process a document (such as a production order, cost center, etc.) that requires a number from a specific number range, but the number you are trying to use is not valid within that range.
  Cause:
  
  Number Range Configuration: The number you are trying to use is outside the defined number range for the object you are working with. Each object in SAP (like production orders, cost centers, etc.) has a specific number range defined in the system.
  Number Range Not Assigned: The number range may not be assigned to the relevant object type, or the number range may be closed for new entries.
  Manual Entry: If you are manually entering a number, it may not fall within the allowed range.
  Number Range Status: The number range might be set to "no more numbers" or "not available" for the current period.
  
  Solution:
  
  
  Check Number Range Configuration:
  
  Go to transaction code SNRO (Number Range Objects).
  Enter the relevant number range object (e.g., for production orders, it might be CO_PROD).
  Check the intervals defined for the number range and ensure that the number you are trying to use falls within the defined range.
  
  
  
  Adjust Number Range:
  
  If the number range is exhausted, you may need to extend the number range. This can be done by:
  
  Going to transaction code SNRO.
  Selecting the appropriate number range object.
  Adding a new interval or extending the existing one.
  
  
  
  
  
  Check Assignment:
  
  Ensure that the number range is correctly assigned to the relevant object type. This can be checked in the configuration settings for the specific module (e.g., Production Planning, Controlling).
  
  
  
  Use Automatic Number Assignment:
  
  If you are manually entering a number, consider allowing the system to automatically assign the next available number instead.
  
  
  
  Consult with SAP Basis or Configuration Team:
  
  If you do not have the necessary authorizations to change number ranges, consult with your SAP Basis or configuration team to resolve the issue.
