Efficient Controls for Accurate and Complete Order Transmission

B.

Out of the given options, the control that most efficiently ensures that orders transmitted from a sales office to a production warehouse are received accurately and completely is A. Transaction totals and record counts should be sent and reconciled before transaction processing.

Explanation:

A. Transaction totals and record counts should be sent and reconciled before transaction processing: This control ensures that the number of transactions sent from the sales office to the production warehouse is equal to the number of transactions received at the warehouse. Additionally, the total value of the transactions sent should match the total value of the transactions received. By comparing the transaction totals and record counts before transaction processing, any errors or omissions can be detected and corrected before production begins. This helps to prevent incomplete or inaccurate orders from being processed.

B. Parity checking should be incorporated into all data transmissions: Parity checking is a method of error detection that involves adding an extra bit to each character to make the total number of bits even or odd. This control can help detect errors during data transmission, but it does not ensure that orders are received accurately and completely.

C. Data should be sent back to the originating site and compared to what was sent to production: This control involves sending data back to the originating site for comparison to what was sent to production. This control can help detect errors during data transmission, but it does not ensure that orders are received accurately and completely.

D. Continuity of numerical sequences for all sales orders should be checked: This control involves checking the continuity of numerical sequences for all sales orders. This control can help detect missing orders, but it does not ensure that orders are received accurately and completely.

Therefore, Option A is the most efficient control to ensure that orders transmitted from a sales office to a production warehouse are received accurately and completely.
