• What is the cause and solution for SAP error message REBDOA018 - &1 cannot be assigned to itself ?

  The SAP error message REBDOA018 typically indicates that there is an issue with the assignment of a business object or entity to itself, which is not allowed in the system. This error often arises in the context of business partner assignments, cost center assignments, or similar scenarios where hierarchical relationships are defined.
  Cause:
  The error occurs when you attempt to assign an object (like a cost center, business partner, or other entities) to itself. This is logically incorrect because it creates a circular reference, which the system does not allow. For example, if you are trying to assign a cost center to itself in a hierarchy, the system will throw this error.
  Solution:
  To resolve this error, you should:
  
  
  Check the Assignment: Review the assignment you are trying to make. Ensure that you are not inadvertently trying to assign the object to itself.
  
  
  Correct the Hierarchy: If you are working with a hierarchy (like cost centers or organizational units), ensure that the parent-child relationships are correctly defined. The object should be assigned to a different object in the hierarchy.
  
  
  Use the Correct Object: If you need to assign an object to another, make sure you are selecting the correct target object that is not the same as the source object.
  
  
  Review Configuration: If this error occurs during a specific transaction or process, review the configuration settings related to that process. Ensure that the settings allow for the intended assignments.
  
  
  Consult Documentation: If you are unsure about the correct assignments, refer to SAP documentation or help resources related to the specific module you are working with (e.g., SAP Controlling, SAP Financials).
  
  
  Related Information:
  
  Transaction Codes: Depending on the context, you may be using specific transaction codes (like OKEQ for cost center assignments) where this error can occur.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. Sometimes, there may be specific fixes or updates provided by SAP.
  User Permissions: Ensure that you have the necessary permissions to make the assignments you are attempting. Lack of permissions can sometimes lead to unexpected errors.
