• What is the cause and solution for SAP error message /ISDFPS/AUTH_DEACT100 - Error: Current logical system &1 is a central system ?

  The SAP error message /ISDFPS/AUTH_DEACT100 indicates that the current logical system is identified as a central system, which typically means that certain operations or configurations that are allowed in non-central systems are restricted in central systems. This error often arises in the context of SAP Landscape Management (LaMa) or when dealing with system authorizations and configurations.
  Cause:
  
  Central System Configuration: The system is configured as a central system (like an SAP S/4HANA system), which has specific restrictions on certain operations, such as deactivating authorizations or making certain changes that are permissible in a non-central system.
  Authorization Issues: The user may not have the necessary authorizations to perform the action in a central system.
  System Landscape: The system landscape may not be set up correctly, leading to confusion about which systems are central and which are not.
  
  Solution:
  
  Check System Type: Verify if the system is indeed a central system. You can do this by checking the system settings in transaction SCC4 or SICF.
  Review Authorizations: Ensure that the user has the necessary authorizations to perform the action. You may need to consult with your SAP Basis or Security team to adjust the roles and authorizations.
  Consult Documentation: Refer to SAP documentation or notes related to the specific transaction or operation you are trying to perform. There may be specific guidelines for central systems.
  Use Appropriate Transactions: If you are trying to deactivate authorizations, consider using transactions that are specifically designed for central systems, or consult with your SAP Basis team for the correct approach.
  SAP Support: If the issue persists, consider reaching out to SAP Support for further assistance, especially if you suspect a configuration issue.
