This error typically arises in the context of the Kanban process within SAP's Production Planning (PP) module, where users are expected to manage inventory and production signals.

  Solution:
  To resolve this issue, follow these steps:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after encountering the error. This will show you the last authorization check and help identify which specific authorization object is missing.

  Check if the roles assigned to the user include the necessary authorizations for the specific plant in question.
  
  
  
  Modify Roles if Necessary:
  
  If the user lacks the required authorizations, you may need to modify the existing roles or create a new role that includes the necessary permissions.
  Work with your SAP security team or administrator to ensure that the roles are updated correctly.
  
  
  
  Testing:
  
  After making changes to the user’s authorizations, have the user log out and log back in to ensure that the new authorizations take effect.
