Final answer:
The materials requisition form is the document that details the description, quantity, and unit cost of direct materials issued for a specific job. It is vital for tracking and recording costs in a job-order costing system.
Step-by-step explanation:
The source document that asks for the description, quantity, and unit cost of the direct materials issued, as well as for the job number, is the materials requisition form. This form is used to record the materials taken from the storeroom and to assign the cost of these materials to specific jobs or cost centers. It plays a crucial role in the job-order costing system where each job is tracked separately. In comparison:
- The job-order cost sheet is a document that records and accumulates all the costs assigned to a specific job.
- The time ticket records the amount of time a worker spends on a particular job.
- The work-in-process inventory file contains information about the goods that are partially completed.
