Final answer:
The management of a TAR request in an MMSYS varies by organization, and the number of days before reentry cannot be determined without specific protocol information.
Step-by-step explanation:
The question pertains to the management and tracking of tasks within a Material Management System (MMSYS). Typically, a Tracer Action Required (TAR) request is related to supply chain or inventory tracking within an organization. However, without specifics on the organization's protocol or the MMSYS in use, it is impossible to provide an accurate number of days after which a TAR request would be reentered into the MMSYS. Organizations often have different protocols for managing their inventory and follow-up actions.
