DD1 means what?

Hi,

My coworker has been wondering what DD1 means?

We both speak french as current language and he asked a parts manufacturer when he was going to receveive the parts.

She replied should arrive on DD1.

What does it means (yes we could just ask her)

JC

My guess is Delivery Date #1.

I dont know how, but I cant see your answer :D

I dont either see other people reply in other threads!

Must be the new forum arrangement haha

Edit: Ok I see the reply when I quote it!

Thanks for the answer!

I see nothing wrong in asking her what she means. I've been in American industry for a long time and I have no idea what she means.
