the root).
This results in a naming conflict in Web Dynpro component &V4&.

• What is the cause and solution for SAP error message SWDP_WB_TOOL194 - Naming conflict (&) in interface controller for comp. interfaces & and & ?

  The SAP error message SWDP_WB_TOOL194 indicates a naming conflict in the interface controller for component interfaces. This typically occurs when there are multiple component interfaces with the same name or when there is a conflict in the naming conventions used in the system.
  Cause:
  
  Duplicate Names: The most common cause is that there are two or more component interfaces defined with the same name in the same namespace or context.
  Incorrect Configuration: Sometimes, the configuration of the component interfaces may not be set up correctly, leading to conflicts.
  Transport Issues: If you are transporting objects between systems, there may be conflicts arising from objects that were not properly managed during the transport process.
  
  Solution:
  
  
  Identify Conflicts:
  
  Use transaction SE80 (Object Navigator) or SE11 (Data Dictionary) to search for the component interfaces that are causing the conflict.
  Check the naming conventions and ensure that each component interface has a unique name.
  
  
  
  Rename Interfaces:
  
  If you find duplicate names, consider renaming one of the interfaces to resolve the conflict. Ensure that the new name adheres to the naming conventions used in your organization.
  
  
  
  Check Configuration:
  
  Review the configuration settings for the component interfaces to ensure they are set up correctly and do not overlap.
  
  
  
  Transport Management:
  
  If the issue arose after a transport, check the transport logs and ensure that all objects were transported correctly. You may need to re-transport or adjust the objects in the target system.
  
  
  
  Clear Cache:
  
  Sometimes, clearing the cache can help resolve issues related to naming conflicts. You can do this by using transaction SE38 and executing the report /IWFND/CL_CACHER.
