• What is the cause and solution for SAP error message LAW2_MESSAGES590 - User types &1 and &2 form loops (import not possible) ?

  The SAP error message LAW2_MESSAGES590 indicates that there is a problem with user types in the context of a data import process. Specifically, it suggests that there are loops formed by the user types involved, which prevents the import from being completed successfully. This error typically arises in scenarios involving user type assignments, such as when dealing with roles, authorizations, or organizational structures.
  Cause:
  
  Circular References: The most common cause of this error is the presence of circular references or loops in the user type assignments. For example, if User Type A is assigned to User Type B, and User Type B is assigned back to User Type A, this creates a loop.
  Incorrect Configuration: Misconfiguration in the user type definitions or relationships can lead to this issue.
  Data Integrity Issues: If the data being imported has inconsistencies or conflicts in user type relationships, it can trigger this error.
  
  Solution:
  
  Review User Type Assignments: Check the user type assignments in the system to identify any circular references. You can do this by reviewing the configuration settings in the relevant transaction codes (e.g., SU01 for user management, PFCG for role management).
  Correct Circular References: If you find any loops, you will need to correct them by removing or reassigning the user types to eliminate the circular dependency.
  Data Validation: Ensure that the data being imported does not contain any inconsistencies or conflicts. Validate the data structure and relationships before attempting the import again.
  Testing: After making the necessary corrections, perform a test import with a smaller dataset to ensure that the issue has been resolved before proceeding with a larger import.
  
  Related Information:
