Question:

Does the Create Draft action end the current active workflow in PromoMats?

Answer:

The document changes to the Draft state if a user with the proper permission selects the Create Draft option from the action menu. The active workflow associated with the previous version remains ongoing.

Example:

A user with the proper permissions selects the Create Draft option from the action menu when the document state is In Review. The document changes to the Draft state but is still in the Review workflow.
