My form has two buttons "Submit" and "Save". Submit will submit the forms library and Save will save it like a Draft Version in library and client can change and after to submit the form. The requirement is: when the client click in "Save" the rule for check if fields with * have value, in this case, doesn't run. How I make the Save Button to that? By code?

You may have to go with custom validation instead of just setting fields to can't be blank. Add a field to your main data source called "status" - when the user clicks the Submit button, set status to submitted. Add validation rules to your fields that have the condition that the field is blank and status = submitted. Then the validation rules only fire when the form had been submitted. You can also clear the errors with code, but validation rules are easier.
