• What is the cause and solution for SAP error message COM_HIERARCHY020 - Enter a numbering scheme; automatic number assignment is active ?

  The SAP error message COM_HIERARCHY020 typically occurs in the context of the SAP Controlling (CO) module, particularly when dealing with the assignment of numbers to cost elements, cost centers, or other hierarchical structures. The error indicates that a numbering scheme needs to be defined because automatic number assignment is active.
  Cause:
  The error arises when:
  
  Automatic number assignment is enabled for a particular object (like cost centers or internal orders).
  There is no numbering scheme defined in the system for that object.
  The system is trying to create a new entry (like a new cost center) but cannot do so because it lacks the necessary configuration for number assignment.
  
  Solution:
  To resolve this error, you need to define a numbering scheme for the relevant object. Here are the steps to do that:
  
  
  Access the Configuration:
  
  Go to the SAP Easy Access screen.
  Navigate to the relevant configuration area. For example, for cost centers, you would go to:
  
  SPRO ? IMG ? Controlling ? Cost Center Accounting ? Master Data ? Cost Center ? Define Number Ranges for Cost Centers.
  
  
  
  
  
  Define Number Ranges:
  
  In the number range configuration, create a new number range or modify an existing one.
  Ensure that the number range is set to allow automatic number assignment.
  
  
  
  Assign the Number Range:
  
  After defining the number range, ensure that it is assigned to the relevant object type (e.g., cost centers, internal orders).
  This assignment links the number range to the automatic number assignment process.
  
  
  
  Check Authorizations:
  
  Ensure that you have the necessary authorizations to make these changes. If not, you may need to contact your SAP administrator.
  
  
  
  Test the Configuration:
  
  After making the changes, try to create the object again to see if the error persists.
  
  
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like OKA0 (for cost center number ranges) or KOT2 (for internal order number ranges) to access the relevant configuration directly.
  Documentation: Refer to SAP Help documentation for detailed steps on configuring number ranges and understanding the implications of automatic number assignment.
  Support: If the issue persists after following the above steps, consider reaching out to your SAP support team or consulting the SAP Community for further assistance.
  
  By following these steps, you should be able to resolve the COM_HIERARCHY020 error and successfully implement automatic number assignment in your SAP system.
