• What is the cause and solution for SAP error message WD098 - Data type &1 cannot be deleted (uses parameter &2) ?

  The SAP error message:
  WD098 Data type &1 cannot be deleted (uses parameter &2)
  Cause:
  This error occurs when you try to delete a data type in the Web Dynpro ABAP repository that is still being used by one or more parameters. The system prevents deletion to avoid inconsistencies or broken references in the application.
  
  &1 = Name of the data type you are trying to delete.
  &2 = Name of the parameter that is still using this data type.
  
  In other words, the data type is referenced by a parameter (e.g., in a method, interface, or context node), so it cannot be deleted until all references are removed.
  Solution:
  
  
  Identify all references to the data type:
  
  Use the SAP Object Navigator (transaction SE80) or the Where-Used List (Shift+F3 or via menu) to find all objects that reference the data type.
  Specifically, look for parameters in methods, interfaces, or context nodes that use this data type.
  
  
  
  Remove or change the references:
  
  Modify the parameters or other objects so that they no longer use the data type you want to delete.
  This might involve changing the parameter type to another data type or deleting the parameter if it is no longer needed.
  
  
  
  Delete the data type:
  
  Once all references are removed, you can delete the data type without error.
  
  
  
  Related Information:
  
  This error is common in Web Dynpro ABAP development when cleaning up unused or obsolete data types.
  Always check dependencies before deleting repository objects to avoid breaking applications.
  Use transaction SE11 (Data Dictionary) or SE80 (Object Navigator) to manage data types and their references.
  The Where-Used List is a powerful tool to find all references to a repository object.
  If the data type is part of a transport request, ensure that all changes are properly transported.
