• What is the cause and solution for SAP error message 01790 - Target client is central system of central user administration ?

  The SAP error message "01790 Target client is central system of central user administration" typically occurs in the context of user administration and client management within an SAP system landscape that utilizes Central User Administration (CUA). This error indicates that the system you are trying to access or perform actions on is a central system in a CUA setup, and certain operations are restricted or not allowed in this context.
  Cause:
  
  Central User Administration (CUA): The error arises when you attempt to perform user management tasks (like creating or modifying users) directly in the central system, which is not permitted. In a CUA setup, user management should be done in the child systems, and the central system is primarily for administration purposes.
  Client Configuration: The target client is configured as a central system, which means it is responsible for managing users across multiple child systems.
  
  Solution:
  
  Use Child Systems for User Management: To resolve this error, you should perform user management tasks in the appropriate child system rather than the central system. Log into one of the child systems and carry out the necessary user administration tasks there.
  Check CUA Configuration: Ensure that your CUA configuration is set up correctly. You can check the configuration in transaction SCUA (Central User Administration) to verify that the central and child systems are properly defined.
  User Management Transactions: Use transactions like SU01 (User Maintenance) in the child systems to create or modify users instead of trying to do it in the central system.
  
  Related Information:
  
  Central User Administration (CUA): CUA allows for centralized management of users across multiple SAP systems. It simplifies user administration by allowing administrators to manage users in one central location.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  SCUA: Central User Administration
  SU01: User Maintenance
  SU10: Mass User Maintenance
  
  
  Documentation: Refer to SAP Help documentation for more details on CUA and user management best practices.
  
  If you continue to experience issues or if the error persists despite following the above steps, it may be beneficial to consult with your SAP Basis team or refer to SAP Notes for any specific patches or updates related to your version of SAP.
