How to name a service operation?

Say that I have a business object called Customer that has the following attributes

ID
Name
Address
   Street
   Postal code
   City
   Country
Credit limit

Now suppose that the Query Customer In service interface already has an operation defined called FindCustomerSimpleByID. That operation has an response message containing ID, Name and Address.

Then I want another operation that returns the ID and CreditLimit base on the ID. The name FindCustomerSimpleByID is already taken. I don't want to add the credit limit to the first operation since it is sensitive data that only some processes should have access to.

What does the eSOA naming convention say in this case?
