• What is the cause and solution for SAP error message /PLMI/ECN_BO002 - Object type &1 is already assigned to change number &2 ?

  The SAP error message /PLMI/ECN_BO002 indicates that an object type (denoted by &1) is already assigned to a change number (denoted by &2). This typically occurs in the context of Engineering Change Management (ECM) within SAP, where objects such as materials, documents, or other engineering items are managed through change numbers.
  Cause:
  
  Duplicate Assignment: The object you are trying to assign to a change number is already linked to another change number. This can happen if the object has already been processed or assigned in a previous change request.
  Incorrect Change Number: You may be trying to assign the object to a change number that is not intended for it, or the change number may be in a status that does not allow further assignments.
  System Configuration: There may be configuration settings in the ECM module that restrict the assignment of certain object types to change numbers.
  
  Solution:
  
  Check Existing Assignments: Verify if the object is already assigned to a different change number. You can do this by checking the change management logs or the object assignment history.
  Use a Different Change Number: If the object is already assigned to a change number, consider using a different change number for your current assignment.
  Release or Close Existing Change Number: If the existing change number is no longer needed, you may release or close it, allowing you to reassign the object to a new change number.
  Review Object Status: Ensure that the object is in a status that allows it to be assigned to a change number. Some statuses may restrict changes.
  Consult Documentation: Review the SAP documentation or help files related to Engineering Change Management for specific guidelines on object assignments.
  Contact SAP Support: If the issue persists and you cannot determine the cause, consider reaching out to SAP support for assistance.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CC01 (Create Change Number), CC02 (Change Change Number), and CC03 (Display Change Number) to manage change numbers effectively.
  Authorization: Ensure that you have the necessary authorizations to assign objects to change numbers.
  Custom Development: If your organization has custom developments or enhancements in the ECM area, check if they might be affecting the standard behavior.
  
  By following these steps, you should be able to resolve the error and successfully manage your object assignments in SAP.
