On these tabs you can view, create and edit project assignments. 

Translation assignments tab:

It's a standard assignment list, but shows only assignments which belong to a currently opened project. From here you can double click any assignment to open it's editing form. To create a new translation assignment, click New, which is the default way of creating entries in SDL Trados Business Manager. The assignment creation form will be opened. Also, above this table you will find the Create assignments button. This button will create a number of empty assignments according to a selected Workflow and existing jobs. Workflow value defines the number of steps (vendors). When you create a new workflow, you only have to specify which service types it includes and in which order. If the source order contains a step defined in a workflow, a new translation assignment will be created. If a job contains a service which is not defined in a workflow, this service will be included in the last assignment. If workflow is not selected, then application will create one assignment per each job which contains any unassigned volumes. It does not depend on service types (for example, if job contains multiple services, like translation, proofreading, editing, then all these services will be included in a single assignment).

Example: You have a job with Translation, Proofreading and Editing services. If you wish to create three assignments (assign a job to three contractors), then the selected workflow must include all these three service types. However, if your workflow only contains the Translation work type, then the system will create one assignment for such job, and include all three services there. If your workflow contains only Translation and Proofreading, then the system will create 2 assignments: first for translation, and second for proofreading and editing.

As a result of this action (Create assignments), the system will create assignments with necessary tasks, with zero amounts and empty Vendor field. Deadlines of assignments will be determined automatically (based on workflow step, project deadline, and assignment volume, comparing to other assignments in a row). When necessary, change deadlines manually when assignments will be created.

If you already know who will performing tasks, select necessary vendors in the Vendor column of the list. It is not mandatory to open assignment editing window - instead, you can select an assignment and click Apply vendor button on the toolbar. The system will apply selected vendor and calculate assignment amount based on a vendor's price list.

To confirm this, you will see some value in the Amount column, and you can switch to the Assignment tasks tab to view which prices have been automatically applied to an assignment:
