Questions on building SOAP services using BW 6

[Kalyan Mudi 3]

I have a few questions around building soap web services using BW6.

1. How to add fault output to an operation added later to an existing port type: I have created a soap service with only one operation, for now, and implemented the operation asconstructor, so that I could keep adding new operations to the same port type later. Now, while creating the first operation, I did have an option to add a fault, along with input/output in the new soap service wizard (in New Interface section). However, when I attempt to add an operation to later, from the Component Service section, the newly created operations are configured with input and output by default. I don't seem to find a place where I can add/configure fault to them.Am I missing something

2. How to change the name of an operation after it has been added: After I have added a new operation, I right click the operation in Component Service section and rename the operation to rename it to something appropriate from the default name ("operation"). However, it appears that, even after renaming in this way, the SOAP Action value in Soap Binding remains the default value and it doesn't change with renaming. Is it expected to change the operatino name in the Soap Action field separately
