Apparently not.

"Debug mode" in DBW means that the SP isn't really executing at all -
it is just being stepped through inside the DBW application to
identify problems in your code.

So check the values that you are passing to your SP that are throwing
the unique key violation.

Sure, if you provide some information about how you are going about
ensuring that your PK field[s] can never receive duplicate values...
