This error can occur in various scenarios, such as when trying to access data or execute a function module that requires specific authorizations.
  Cause:
  
  Missing Authorizations: The user executing the RFC call does not have the required authorizations assigned in their user profile. This could be due to missing roles or authorizations related to the specific function module or transaction.
  Role Configuration: The roles assigned to the user may not include the necessary permissions to unpack lists or access certain data.
  Profile Issues: The user profile may not be correctly configured, or there may be restrictions in place that prevent the user from executing the required actions.
  
  Solution:
  
  
  Check User Authorizations:

  Review the roles assigned to the user and ensure that they include the necessary authorizations for the function being called.
