Each department, or shop, should be supplied with storeroom requisitions, numbered consecutively with the department number or letter; that is, a requisition from one shop might be numbered _B_ 100, another _C_ 100. These requisitions should be made in duplicate or triplicate. When the duplicate form is used, the original is sent to the stores clerk and the duplicate retained by the foreman. When the stores clerk has completed his records and the foreman has received the material, both copies are to be sent to the cost department. One copy acts as a check against the other, making it impossible for either the stores clerk or foreman to make false returns. To make identification easy, the two blanks should be printed on paper of contrasting colors. In the cost department one copy should be filed according to the department in which the requisition originated, keeping the numbers consecutive, and the other under the production or job order number. On completion of the order, the latter copy can be destroyed as it will no longer be needed. The departmental copies may also be destroyed, say at the end of a three months' period. Sometimes it will be found advisable for the stores clerk to retain a copy of the requisition, in which event the triplicate form will be used, two copies being sent to him. He will file his copy by production order numbers, if for material, or by departmental numbers, if for supplies. All requisitions should provide for a record of prices and values, these to be entered in the cost department. If this is omitted it will be necessary for the cost clerk to enter the items and extend cost on another blank; when included, he can post values direct from the requisition to the permanent cost records. Place should also be provided on the requisition for the signature of the one who receives the material. [Illustration: Fig. 23. Requisition for Material to be Used on a Production Order] A form of requisition adapted to the use of the average manufacturing enterprise is shown in Fig. 23. This form shows the _department number_, the _date_, the _production order number_, _quantity_, _description_, _cost_, and _value_. At the bottom the necessary _form of receipt_ is provided. Usually this form will be found adequate for both material and supplies. When used for supplies, the purpose for which they are intended is to be inserted in place of the production order number. Special forms for supplies and repair material are used in some plants. These should differ in color from the _material_ requisitions. A form of this character is illustrated in Fig. 24. STORES RECORDS =23.= The installation of a stores─record system calls for the exercise of judgment of the highest order, for the record of material and supplies is of no less importance than the record of cash. As has already been stated, material should be accounted for with the same fidelity as cash; a dollar's worth of material should be regarded as a dollar in gold.
