• What is the cause and solution for SAP error message LDAPSYNC001 - In CUA landscape, synchronization is only allowed in the central system ?

  The error message LDAPSYNC001 in an SAP environment indicates that there is an issue with the synchronization of user data in a Central User Administration (CUA) landscape. Specifically, it states that synchronization is only allowed in the central system. This typically occurs when there is an attempt to synchronize user data from a child system rather than the central system.
  Cause:
  
  CUA Configuration: In a CUA landscape, user management is centralized in the central system. Child systems are meant to receive user data from the central system, not to initiate synchronization.
  LDAP Synchronization Attempt: The error may occur if there is an attempt to perform LDAP synchronization from a child system instead of the central system.
  Incorrect System Role: The system from which the synchronization is being attempted may not be configured correctly as a central or child system.
  
  Solution:
  
  Perform Synchronization in Central System: Ensure that any LDAP synchronization is initiated from the central system. This is where user data is managed and should be the only system performing synchronization tasks.
  Check CUA Configuration: Verify the configuration of the CUA setup to ensure that the roles of the systems (central vs. child) are correctly defined.
  Review User Management Settings: Check the user management settings in the central system to ensure that they are correctly set up for LDAP synchronization.
  Use Transaction Codes: Use transaction codes like SU01 for user management and SCUA for CUA administration to manage users and check configurations.
  Consult Documentation: Refer to SAP documentation for CUA and LDAP synchronization for detailed steps and best practices.
