{note}
The details shows the local worker service name i.e. if you inserted a *Read Swiss Prot File* service into your workflow and renamed it *read_data*, then the details will show *Read Swiss Prot File*.

You will be asked for confirmation that you want to edit the script. If you change the script, then the local service will become a Beanshell service.

The details of the modified service will indicate that that it is altered and what it was originally.
