• What is the cause and solution for SAP error message ACM066 - Authorization field &1 of authorization object &2 can only be used once ?

  The SAP error message ACM066 indicates that there is an issue with the authorization object configuration in the system. Specifically, it means that a particular authorization field (denoted as &1) within an authorization object (denoted as &2) has been defined more than once, which is not allowed.
  Cause:
  
  Duplicate Authorization Fields: The error typically arises when the same authorization field is included multiple times in the definition of an authorization object. Each field in an authorization object must be unique.
  Custom Authorization Objects: If you are working with custom authorization objects, it is possible that during the creation or modification of the object, the same field was inadvertently added more than once.
  Transport Issues: Sometimes, transport requests that include authorization objects can lead to inconsistencies if not handled properly.
  
  Solution:
  
  
  Check Authorization Object Definition:
  
  Go to transaction code SU21 (Maintain Authorization Objects).
  Locate the authorization object in question (using the name provided in the error message).
  Review the fields defined in the object and ensure that each field is unique. Remove any duplicate fields.
  
  
  
  Modify the Authorization Object:
  
  If you find duplicates, modify the authorization object to remove the duplicate field(s).
  Save your changes and transport them if necessary.
  
  
  
  Testing:
  
  After making changes, test the authorization object to ensure that it works as expected and that the error message no longer appears.
  
  
  
  Consult Documentation: If you are unsure about the implications of modifying an authorization object, consult SAP documentation or your security team for guidance.
  
  
  Related Information:
