Can the quantity of a requisition be modified once it is submitted?

The correct response indicates that once a requisition is submitted, it cannot be modified. This reflects standard practices in supply chain management, where an approved requisition is often considered a formal request for items or services. After submission, the integrity of the procurement process is maintained by not allowing changes unless specific protocols are followed, which often necessitate submitting an entirely new requisition or formally canceling the original one.

This practice helps ensure accountability and traceability within the procurement process, as any modifications after submission could lead to confusion, errors, or unauthorized changes in inventory levels. Thus, adherence to the policy of not allowing modifications post-submission is critical for maintaining accurate records and effective inventory management within the USMC supply requisition system.
