  The SAP error message /ISDFPS/USER_DISTRIB004 CUA is not active in logical system &1 typically indicates that the Central User Administration (CUA) is not activated for the specified logical system in your SAP landscape. This can occur in environments where CUA is used to manage user data across multiple SAP systems.
  Cause:
  
  CUA Not Activated: The logical system specified in the error message does not have CUA activated. This means that the system is not set up to receive user data from the central system.
  Configuration Issues: There may be configuration issues in the CUA setup, such as incorrect logical system settings or missing authorizations.
  Network Issues: There could be network connectivity issues between the central system and the child system.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check CUA Activation:
  
  Go to the transaction SU01 in the central system and check if the logical system (as indicated by &1 in the error message) is listed and active in the CUA configuration.
  Use transaction SCUA to check the CUA settings and ensure that the logical system is included in the CUA setup.
