• What is the cause and solution for SAP error message WS_TOOL160 - Type is still used for input parametr &1 ?

  The SAP error message:
  WS_TOOL160 Type is still used for input parameter &1
  typically occurs in the context of Web Services or Enterprise Services development, especially when working with the Web Service Tool (transaction SE80 or SOAMANAGER) or when trying to change or delete a data type that is still referenced by an input parameter of a function module, method, or service interface.
  
  Cause
  
  The data type you are trying to modify or delete is still referenced as an input parameter in one or more function modules, methods, or service interfaces.
  SAP prevents changes or deletion of data types that are actively used to avoid inconsistencies or runtime errors.
  The placeholder &1 in the message will be replaced by the name of the input parameter that is still using the type.
  
  
  Explanation
  When you define or modify Web Service interfaces or function modules, the parameters (input/output) are typed with data types (structures, tables, elementary types). If you try to delete or change a data type that is still assigned to an input parameter, SAP will block this action and show this error message.
  
  Solution
  
  
  Identify where the type is used:
  
  Use transaction SE11 (Data Dictionary) to check where the type is used.
  In SE11, enter the data type name, then go to Utilities > Where-Used List.
  Select "In Function Modules" or "In Programs" or "In Classes" to find references.
  Alternatively, use SE80 or SE84 to search for references.
  
  
  
  Check the input parameter:
  
  Once you find the function module, method, or service interface using the type as an input parameter, you need to:
  
  Change the parameter type to another data type if you want to delete or modify the original type.
  Or delete the function module/method/service interface if it is no longer needed.
  
  
  
  
  
  Adjust or remove references:
  
  Modify the interface to use a different data type.
  Or remove the interface if it is obsolete.
  
  
  
  After removing all references:
  
  You can then safely modify or delete the data type.
  
  
  
  
  Additional Notes
  
  Be careful when changing data types used in interfaces, as this can impact existing programs or services.
  Always check for transport requests and dependencies.
  If the type is used in Web Service definitions, you may need to regenerate or adjust the service after changes.
  Sometimes, the error can occur during Web Service generation or proxy generation if the underlying data types are inconsistent.

  Data type is still assigned to an input parameter of a function module/method/service.
  
  
  Effect
  SAP blocks modification or deletion of the data type to prevent inconsistencies.
  
  
  Solution
  Find and remove/change all references to the data type in input parameters, then retry.
