Overview:
Multi-document workflows allow a user to send a collection of documents out for review and perform approval on a single workflow instance. The user can start multi-document workflows from the Library, Cart, or a Binder section.
When a user starts a multi-document workflow, an error appears and indicates the specific state is not defined in the lifecycle.

Root Cause:
The state is not defined in the Details page of a single document lifecycle. This results in no linkage for the states between the single document lifecycle and the multi-document workflows.
Solution:
As a Vault admin:
- Navigate to Admin --> Configuration --> Document Lifecycles.
- Select the lifecycle to which documents belong.
- Ensure the specific state is defined in the Details page of the lifecycle.
