• What is the cause and solution for SAP error message LM136 - Number range & reserved for external assignment ?

  The SAP error message LM136, which states "Number range & reserved for external assignment," typically occurs when you are trying to assign a number to a document or object that falls within a number range that has been reserved for external assignment. This means that the number range is not available for internal use, and the system is preventing you from using it.
  Cause:
  
  Number Range Configuration: The number range you are trying to use is configured in the system to be reserved for external assignment. This is often done to ensure that certain numbers are generated externally (e.g., from an external system) and not internally by SAP.
  Incorrect Number Range Assignment: The document or object you are trying to create or modify is incorrectly assigned to a number range that is not meant for internal use.
  Custom Development: If there are custom developments or enhancements in your SAP system, they might be incorrectly configured to use a reserved number range.
  
  Solution:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects).
  Find the relevant number range object associated with the document or object you are working with.
  Check the configuration to see if the number range is indeed set for external assignment. If it is, you may need to use a different number range that is available for internal assignment.
  
  
  
  Change Number Range Assignment:
  
  If you have the necessary authorizations, you can change the assignment of the document or object to a different number range that is not reserved for external assignment.
  This can usually be done in the customizing settings for the specific module you are working with.
  
  
  
  Consult with Basis or Development Team:
  
  If you are unsure about changing the configuration or if the number range is part of a custom development, consult with your SAP Basis or development team. They can provide insights into the implications of changing number range settings.
  
  
  
  Use External Number Assignment:
  
  If the business process requires using the external number range, ensure that the external system is correctly configured to generate and assign numbers as needed.
