Information:

The Moraine Company is a discount tire dealer that operates $25$ retail stores in a metropolitan area. The company maintains a centralized purchasing and warehousing facility and employs a perpetual inventory system. All purchases of tires and related supplies are placed through the company$$s central purchasing department to take advantage of the quantity discounts offered by its suppliers. The tires and supplies are received at the central warehouse and distributed to the retail stores as needed. The perpetual inventory system at the central facility maintains current inventory records, which include designated reorder points, optimal order quantities and balance on hand information for each type of inventory.

The participants involved in Moraine$$s inventory system include $(1)$ retail stores, $(2)$ the inventory control department, $(3)$ the warehouse, $(4)$ the purchasing department, $(5)$ accounts payable and $(6)$ outside vendors. The inventory control department is responsible for maintenance of the perpetual inventory records for each item carried in inventory. The warehouse department maintains the physical inventory of all items carried by the company$$s retail stores.

All deliveries of tires and related supplies from vendors are received by receiving clerks in the warehouse department and all distributions to retail stores are filled by shipping clerks in this department. The purchasing department places every order for items needed by the company. The accounts payable department maintains the subsidiary ledger with vendors and other creditors. All payments are processed by this department. The documents used by these various departments are as follows:

The retail stores submit Retail Store Requisitions $($RSR$)$ to the central warehouse whenever tires or supplies are needed at the stores. The shipping department clerks in the warehouse department fill the orders from inventory and have them delivered to the stores. Three copies of the document are prepared, two of which are sent to the warehouse, and the third copy is filed for reference.

An inventory control clerk in the inventory control department prepares purchase requisitions $($PR$)$ when the quantity on hand for an item falls below the designated reorder point. Two copies of the document are prepared. One copy is forwarded to the purchasing department and the other is filed.

The purchasing department prepares purchase orders $($PO$)$ based on the information found on the purchase requisition. Five copies of the purchase order are prepared. The disposition of these copies is as follows: copy $1$ to vendor, copy $2$ to accounts payable, copy $3$ to inventory control department, copy $4$ to warehouse and copy $5$ filed for reference.

The warehouse department prepares the receiving reports $($RR$)$ when ordered items are received from vendors. A receiving clerk completes the document by indicating the vendor$$s name, the date the shipment was received and the quantity of each item received. Four copies of the report are prepared. Copy $1$ is sent to the accounts payable department, copy $2$ to the purchasing department, copy $3$ to the inventory control department, and copy $4$ is retained by the warehouse department, compared with the purchase order form in its files, and filed together with this purchase order form for future reference.

Invoices received from vendors are bills for payment. The vendor prepares several copies of each invoice, but only two copies are of concern to the Moraine Company. The copy that is received by the company$$s accounts payable department and the copy that is retained by the vendor for reference. The accounts payable department compares the vendor invoice with its copy of the original purchase order and its file copy of the warehouse receiving report. ON the basis of this information, adjustments to the bill amount on the invoice are made $($for damaged goods, trade discounts, cash discounts, etc.$),$ a check is prepared and payment is made to the vendor by check.
