Consider the following partial description of the expenditure cycle process:

An inventory control clerk examines the inventory records for items that must be replenished and prepares

a two-part purchase requisition. Copy 1 of the requisition is sent to the purchasing department, and Copy 2

is filed.

Upon receipt of the requisition, the purchasing clerk selects a supplier from the valid vendor file (reference

file) and prepares a three-part purchase order. Copy 1 is sent to the supplier, Copy 2 is sent to the accounts

payable department where it is filed temporarily, and Copy 3 is filed in the purchases department.

A few days after the supplier ships the order, the goods arrive at the receiving department. They are

inspected, and the receiving clerk prepares a three-part receiving report describing the number of quality of

the items received. Copy 1 of the receiving report accompanies the goods to the stores (inventory), where

they are secured. Copy 2 is sent to inventory control, where the clerk posts it to the inventory records and

files the document. Copy 3 is sent to the accounts payable department, where it is filed with the purchase

order.

Required: Prepare a data flow diagram of the expenditure cycle process described above.
