Final answer:
Preformatted screens in the OE/S process are not a control plan involving detailed comparison of elements on two source documents; they are designed to facilitate accurate data entry.
Step-by-step explanation:
The statement that preformatted screens in the OE/S (Order Entry/Source) process are a control plan involving the detailed comparison of the individual elements appearing on two source documents is false.
Preformatted screens in the OE/S process are used to help in the accurate and efficient entry of data. They are designed to ensure that all the necessary fields are completed during the order entry process, and do not necessarily involve a detailed comparison of two source documents.
The control plan that might involve such a detailed comparison is more typically associated with verification or reconciliation processes, where the accuracy of data entry is checked against original source documents.
