• What is the cause and solution for SAP error message SWDP_WB_TOOL218 - The selected component is identical with the basis component ?

  The SAP error message SWDP_WB_TOOL218, which states "The selected component is identical with the basis component," typically occurs in the context of SAP Web Dynpro development. This error indicates that the component you are trying to create or modify is the same as the basis component, which is not allowed in the context of component inheritance or extension.
  Cause:
  The error arises when you attempt to create a new component or a new version of an existing component that is identical to the basis component. This can happen in scenarios where:
  
  You are trying to create a new component based on an existing one but mistakenly select the same component as the basis.
  There is a misunderstanding in the component hierarchy or structure, leading to an attempt to extend or modify a component that is already the same as the one you are working on.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Component Selection: Ensure that you are selecting a different component as the basis for your new component. The basis component should be a parent or a different component that you want to extend or modify.
  
  
  Create a New Component: If you intended to create a new component, make sure to provide a unique name and select a valid basis component that is not the same as the one you are currently working on.
  
  
  Review Component Hierarchy: If you are working with component inheritance, review the hierarchy of your components to ensure that you are following the correct structure. The basis component should be a valid parent component.
  
  
  Use the Correct Development Environment: Make sure you are using the appropriate development environment (like the Web Dynpro Workbench) and that you have the necessary authorizations to create or modify components.
  
  
  Consult Documentation: If you are unsure about the component structure or the process, refer to the SAP documentation or help resources related to Web Dynpro development for guidance.
