• What is the cause and solution for SAP error message UAS104 - No types defined, function not possible ?

  The SAP error message UAS104 ("No types defined, function not possible") typically occurs in the context of SAP's User Administration Services (UAS) or when dealing with user types in the system. This error indicates that the system is unable to find the necessary type definitions required to perform a specific function related to user administration.
  Cause:
  
  Missing Configuration: The error often arises when there are no user types defined in the system. This could be due to a lack of configuration in the user administration settings.
  Custom Development Issues: If there are custom developments or enhancements that rely on specific user types, and those types are not defined, this error can occur.
  Transport Issues: If the system has recently undergone a transport that included user type definitions, and those definitions were not properly imported, it could lead to this error.
  Authorization Issues: Sometimes, the user executing the function may not have the necessary authorizations to access the user types.
  
  Solution:
  
  
  Define User Types: 
  
  Go to the relevant configuration transaction (usually in the User Administration area) and ensure that the necessary user types are defined.
  You can check the configuration in transaction SU01 (User Maintenance) or SU10 (Mass User Maintenance) to see if user types are set up correctly.
  
  
  
  Check Custom Code: 
  
  If there are custom programs or enhancements, review the code to ensure that it correctly references existing user types.
  Make sure that any custom logic does not assume the existence of user types that have not been defined.
  
  
  
  Transport Management: 
  
  If the issue arose after a transport, check the transport logs to ensure that all necessary objects were transported correctly.
  If needed, re-import the transport or manually create the missing user types.
  
  
  
  Authorization Check: 
  
  Verify that the user encountering the error has the necessary authorizations to access user types. This can be done by checking the user's roles and authorizations in transaction SU53 or SUIM.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or notes related to user administration and the specific function you are trying to execute. There may be specific notes or patches that address this issue.
