• What is the cause and solution for SAP error message CP118 - Internal number assignment not possible ?

  The SAP error message CP118 ("Internal number assignment not possible") typically occurs in the context of internal number ranges, particularly when the system is unable to assign a new internal number for a document or object due to various reasons. Here are some common causes, solutions, and related information for this error:
  Causes:
  
  Exhausted Number Range: The internal number range defined for the object may be exhausted, meaning that all possible numbers have been assigned.
  Number Range Configuration: The number range may not be properly configured or may not be active for the relevant document type.
  Authorization Issues: The user may not have the necessary authorizations to access or modify the number range.
  System Settings: There may be issues with the system settings or configuration that prevent the assignment of new numbers.
  Date Validity: The number range may be restricted by date, and the current date may fall outside the valid range.
  
  Solutions:
  
  
  Check Number Range Status:
  
  Go to transaction code SNRO (Number Range Objects) and check the status of the number range object related to the error.
  Ensure that the number range is not exhausted and that there are available numbers.
  
  
  
  Adjust Number Range:
  
  If the number range is exhausted, you may need to extend it. This can be done in transaction code SNRO or OBA7 (for financial documents).
  Ensure that the number range is set to "Internal" if it is supposed to be automatically assigned by the system.
  
  
  
  Review Configuration:
  
  Check the configuration settings for the relevant document type in the customizing settings (transaction code SPRO).
  Ensure that the number range is correctly assigned to the document type.
  
  
  
  Check Authorizations:
  
  Verify that the user has the necessary authorizations to create or modify the document that requires the internal number assignment.
  
  
  
  Consult System Logs:
