• What is the cause and solution for SAP error message ATC_UI002 - Primary parameter already exists ?

  The SAP error message ATC_UI002 ("Primary parameter already exists") typically occurs in the context of the ABAP Test Cockpit (ATC) or Code Inspector when there is an attempt to define a parameter that already exists in the configuration. This can happen when you are trying to create or modify a check variant or a configuration that includes parameters that are already defined.
  Cause:
  
  Duplicate Parameter Definition: The error is primarily caused by trying to create a new parameter with the same name as an existing one in the ATC configuration.
  Configuration Overlap: If you are importing or copying configurations, there may be a conflict with existing parameters.
  
  Solution:
  
  
  Check Existing Parameters: Review the existing parameters in the ATC configuration to identify if the parameter you are trying to create already exists. You can do this by navigating to the relevant ATC configuration settings.
  
  
  Rename the Parameter: If you need to create a new parameter, consider renaming it to avoid the conflict with the existing one.
  
  
  Modify Existing Parameter: If the parameter you are trying to create is intended to replace or modify an existing one, consider editing the existing parameter instead of creating a new one.
  
  
  Delete Unused Parameters: If there are parameters that are no longer needed, you can delete them to free up the name for new definitions.
  
  
  Consult Documentation: Refer to the SAP Help documentation or the ATC configuration guide for more detailed instructions on managing parameters.
