• What is the cause and solution for SAP error message M3866 - No authorization to change back-posting in this company code ?

  The SAP error message M3866, which states "No authorization to change back-posting in this company code," typically occurs when a user attempts to perform a back-posting operation in a company code for which they do not have the necessary authorizations.
  Cause:
  
  Authorization Issues: The user does not have the required authorization to perform back-posting in the specified company code. This can be due to missing roles or permissions in the user's profile.
  Company Code Restrictions: The company code may have specific restrictions or settings that prevent certain users from making changes.
  User Role Configuration: The roles assigned to the user may not include the necessary transaction codes or authorizations related to back-posting.
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs to check the authorization failure. This will show which specific authorization object is missing.
  Review the user's roles and authorizations in transaction code SU01 or PFCG.
  
  
  
  Modify User Roles:
  
  If the user lacks the necessary authorizations, a security administrator or SAP Basis team member should update the user's roles to include the required permissions for back-posting in the relevant company code.
  Ensure that the user has the appropriate authorization objects, such as M_BEST_BSA (for purchasing documents) or M_BEST_EKO (for company code-specific authorizations).
  
  
  
  Consult with Security Team:
  
  If you are not authorized to change roles, contact your SAP security team or administrator to request the necessary changes.
  
  
  
  Review Company Code Settings:
  
  Check if there are any specific settings or configurations in the company code that might restrict back-posting. This can include settings in the financial accounting module.
  
  
  
  Testing:
  
  After changes are made, have the user log out and log back in to ensure that the new authorizations take effect. Then, attempt the back-posting operation again.
