  Solution:
  To resolve this issue, you can follow these steps:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs to see which authorization check failed. This will provide insight into what specific authorization is missing.
  
  
  
  Review Role Assignments:
  
  Check the roles assigned to the user in transaction SU01 (User Maintenance). Ensure that the user has the necessary roles that include the required authorizations.

  Use transaction PFCG (Role Maintenance) to manage roles and authorizations.
  
  
  
  Add Required Authorizations:
  
  Ensure that the role includes the necessary authorization objects, particularly S_COMT. You may need to add specific activity authorizations (like change or display) for the communication assembly.
  
  
  
  Testing:
  
  After making changes to the roles and authorizations, have the user log out and log back in to ensure that the new authorizations take effect. Then, attempt the action that caused the error again.
