In translation assignment you can "describe" work using two tables: Assignment tasks and Payables.

Assignment tasks table is obligatory, as it determines volumes of a base translation job which are assigned to a selected vendor. Assignment task can be linked with base job task (to track assigned and unassigned volumes), as well as not linked (if such tracking isn't required).

Quantity initial column specifies a volume in source job task's units. This value will be deducted from the initial source job task quantity to track assigned and non-assigned volumes. Initial unit is a non-editable field which just displays units used in the source job task.

In the Quantity column you specify a volume which will be assigned to a selected vendor. This quantity is expressed in units specified in the Unit filed. By default, value in the Unit field equals to the Initial unit value. However, you can change it, if you need to convert source units into different units. It could be done automatically (see automatic unit conversion settings for a vendor), or manually, by manually selecting different unit or by using Convert to another unit button on the toolbar above the Assignment tasks table.

You can use Quantity unassigned column as a reference to know how much is still possible to assign to vendors. This is particularly useful when you assign the same job task to multiple vendors. When you change a number in the Quantity column, value in the Quantity unassigned column will be immediately changed.

Payables table It allows to "override" data entered in the Assignment tasks table to separate invoice contents from the actual tasks specified in the Tasks table. This table can be used in following cases:

• to join multiple tasks into one task (multiple fuzzy types into one "average" volume, or multiple services into some single service with average price, to keep an invoice short);
• to enter specific calculation of task (for example, when job is very small and contractor has minimal charge).

Underlining, the following workflow is used when translation assignment is created:

1. You add all job tasks which will be assigned to a contractor and enter assigned quantities in units which are specified in base job tasks.
   1. If possible, you just specify contractor's prices for each task, save an assignment and print PO. Payables table is not used.
   2. If point a does not fit requirements of a current assignment, you switch to the Payables tab and create necessary rows to describe all paid items for an assignment. In this case, amount of assignment is calculated from Payables table, instead of Assignment tasks table. But actual work required from a vendor is anyway listed on the Tasks tab.
