• What is the cause and solution for SAP error message VO020 - You are not authorized to save picking waves ?

  SAP Error Message:
  
  VO020 - You are not authorized to save picking waves
  
  Cause:
  This error occurs because the user attempting to save a picking wave does not have the necessary authorization. In SAP Warehouse Management (WM) or Extended Warehouse Management (EWM), certain activities like creating or saving picking waves require specific authorizations. If the user’s role or profile lacks these authorizations, the system prevents the action and throws the VO020 error.
  
  Explanation:
  
  Picking Wave: A picking wave is a group of warehouse orders or deliveries that are released together for picking.
  Authorization Check: SAP checks if the user has the required authorization object(s) to perform the save operation on picking waves.
  The missing authorization is typically related to the authorization object L_WAVE_VC (Wave Control) or similar, depending on the SAP system version and configuration.
  
  
  Solution:
  
  
  Identify Missing Authorization:
  
  Check the authorization object related to picking waves, commonly L_WAVE_VC.
  Use transaction SU53 immediately after the error occurs to see which authorization check failed.
  Alternatively, check the system log or developer trace for authorization failures.
  
  
  
  Update User Roles:
  
  Add the required authorization object(s) to the user’s role/profile.
  For example, include the authorization object L_WAVE_VC with appropriate activity (e.g., activity 02 = Change, 03 = Display, 06 = Save).
  Ensure the organizational levels (plant, warehouse number, etc.) are correctly maintained in the authorization.
  
  
  
  Transport and Test:
  
  After updating the role, transport the changes if necessary.
  Test the user’s ability to save picking waves again.
  
  
  
  Consult Security Team:
  
  If you do not have authorization to change roles, coordinate with your SAP security or BASIS team.
  
  
  
  
  Related Information:
  
  Transaction Codes:
  
  Picking wave creation and management might be done in transactions like /SCWM/WAVE (EWM) or LT03 (classic WM).
  
  
  Authorization Object:
  
  L_WAVE_VC – Wave Control
  Activities: 01 (Create), 02 (Change), 03 (Display), 06 (Save)
  
  
  SAP Notes:

  SU53 Usage:

  Summary:
  
  Cause: Missing authorization to save picking waves.
  Solution: Add the required authorization object(s) (e.g., L_WAVE_VC) with appropriate activities to the user’s role.
  Check: Use SU53 to identify missing authorizations and coordinate with security team to update roles.
