• What is the cause and solution for SAP error message UMV018 - You are not authorized to change hierarchy ?

  The SAP error message UMV018 ("You are not authorized to change hierarchy") typically occurs when a user attempts to modify a hierarchy in the SAP system but lacks the necessary authorizations to perform that action. This error is common in modules that involve hierarchical data structures, such as SAP Master Data Governance (MDG) or SAP Business Warehouse (BW).
  Cause:
  The primary cause of this error is insufficient authorization. The user account attempting to make changes to the hierarchy does not have the required permissions assigned in the authorization roles. This can happen due to:
  
  Missing Authorization Objects: The user may not have the necessary authorization objects assigned to their role that allow for hierarchy changes.
  Role Configuration: The roles assigned to the user may not include the necessary permissions for the specific hierarchy or organizational unit they are trying to modify.
  Hierarchy Locking: The hierarchy might be locked for changes due to ongoing processes or settings in the system.
  
  Solution:
  To resolve the UMV018 error, you can take the following steps:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs to check the authorization check that failed. This will provide insight into which specific authorization object is missing.
  Review the user's roles and authorizations in transaction SU01 or PFCG.
  
  
  
  Modify Roles:
  
  If you have the necessary administrative rights, you can modify the user's roles in transaction PFCG to include the required authorization objects. Common authorization objects related to hierarchy changes include:
  
  S_HIER (Hierarchy Management)
  S_TCODE (Transaction Code)
  
  
  Ensure that the roles include the necessary permissions for the specific hierarchy or organizational unit.
  
  
  
  Consult with Security Team:
  
  If you do not have the necessary access to modify roles, contact your SAP security or basis team. Provide them with the details of the error and the transaction you were trying to perform.
  
  
  
  Check Hierarchy Locking:
  
  Verify if the hierarchy is locked for changes. This can be due to ongoing processes or settings in the system. If it is locked, you may need to wait until the lock is released or consult with the relevant team to unlock it.
  
  
  
  Documentation and Training:
  
  Ensure that users are trained on the proper procedures for making changes to hierarchies and understand the authorization requirements.

  By following these steps, you should be able to identify the cause of the error and implement the necessary changes to resolve it.
