• What is the cause and solution for SAP error message LAW2_MESSAGES603 - External system &1 is already assigned to LAW system &2 ?

  The SAP error message LAW2_MESSAGES603 indicates that there is an issue with the assignment of an external system to a Landscape Management (LAW) system. Specifically, it means that the external system you are trying to assign is already linked to another LAW system.
  Cause:
  
  Existing Assignment: The external system (e.g., a client or a database) is already assigned to a different LAW system. This can happen if the same external system is being used in multiple LAW configurations.
  Configuration Error: There may be a misconfiguration in the LAW setup, leading to conflicts in system assignments.
  Data Consistency Issues: There might be inconsistencies in the LAW configuration data, possibly due to previous changes or migrations.
  
  Solution:
  
  
  Check Existing Assignments:
  
  Go to the LAW configuration and check the current assignments of the external system. Identify which LAW system it is currently assigned to.
  If the external system is indeed assigned to another LAW system and you want to change this, you will need to remove it from the current assignment first.
  
  
  
  Remove Existing Assignment:
  
  If you have the necessary permissions, you can remove the external system from its current LAW system assignment. This can typically be done in the LAW configuration interface.
  After removing the assignment, you can then proceed to assign the external system to the desired LAW system.
  
  
  
  Consult Documentation:
  
  Refer to the official SAP documentation for Landscape Management to ensure you are following the correct procedures for system assignments.
  
  
  
  Check for Data Consistency:
  
  If you suspect data consistency issues, you may need to run consistency checks or consult with your SAP Basis team to ensure that the LAW configuration is correct.
  
  
  
  Contact SAP Support:
