# File based generation action that leads to generation wizard

This topic describes the ability to start the generation wizard function from a source file.

In an Enterprise Service Tools single-service project, the generate action on a source file will lead to the generation wizard. Also, the generate action on a source file will lead to the generation wizard with all customization if the selected source file is the same as the one selected in the prior session, i.e. the behavior will be similar to selecting generate action on the EST project. If the selected source file is a different file, a warning message is displayed indicating that all customization would be ignored.

Scope:

Applicable to:

- Bottom-up development (Enable existing enterprise applications as Web services)
- Top-down development (create a Web service implementation for a Web service)

Not applicable to: Meet-in-middle development (Map to an Existing Service Interface)
