It is possible to book a new CDR before you even created the Drawing, in the case you want to create the drawing afterward and need to assign a specific CDR to it.

In this case, access the Design Code profile card either from the “Team search” menu in the Table of Content or from any other object assigned with the same Design Code.

From the Team profile card, either click on the following icon in the header,

Or click on “Book a new CDR” in the “Booked CERN Drawing References” tab ,in the right-hand side of the ribbon:

In the following open window, enter a reason for the booking action as well as all the required properties (marked with a red star). Confirm. 

In case you are not using the "Sequence", the system will book the next available CDR deriving from the Design Code.

The CDR you just booked is now appearing in the “Booked CERN Drawing References” table and will be available to be set on a Drawing assigned with the same Design Code. Please follow the instructions of the following How to to assign that CDR to a Drawing.

Note:

You need to have one of the following roles to be able to book a new CDR: Contributor, Design Reviewer, or Equipment Owner.
