Cancellation of dependent appointment

Hi Kumar,
My H1B is fresh (first timer). My company has booked an appointment with dependents (D160 is linked). Now my dependents are not available due to some issues and only I need to appear for interview.
what are the options for me:

  1. Should go alone without dependents. will it have an issue?
  2. Should I ask to cancel this one and re-book another one at a later date? what is the procedure? will i have to submit D160 again?
