What can trigger the automatic deletion of outdated material reservations?

The automatic deletion of outdated material reservations is primarily linked to the establishment of a retention period. When a retention period is set for material reservations, it defines how long a reservation will be valid. Once this period expires, the system recognizes that the reservation is no longer relevant or needed, prompting the automatic deletion of these outdated reservations. This helps maintain data accuracy and prevents clutter in the system from outdated reservations that can hinder the efficiency of material planning and inventory management.

Other options, while related to materials management, do not specifically trigger the deletion of outdated reservations: a material availability check ensures that materials are available for production but does not affect the status of reservations; the completion of production orders pertains to the processing of those orders rather than managing reservations; and inventory reconciliation focuses on aligning physical stock with recorded stock levels, which does not directly involve the management of reservations over time.
