Service operations schema issue

Hi All,

I am using standard document service (Customer service).

There are more than 350 fields in the customer table, in the WSDL URL it's showing all the fields, I am expecting only 5fields to display in the schema.

I have made changes in the data policies to enable only the required fields and I can see only the required fields in the data policies parameter schema, but when I select the service operation schema it's showing all the fields.
