The longest lead time required to provide a component (including subrotables and consumables) or PRT (Production Resources and Tools) that is currently unavailable.The CMC uses a "worst-case" scenario.
If the workshop performs manual ATP checks on required components, the CMC provides information on the availability of these components (including sub-rotables and consumables) or PRT so that workshops can analyze critical situations (i.e. non-availability of spares may stop work on an order). If it is not possible to provide the required component at the right time, the CMC displays the "worst" replenishment lead time. First, the CMC checks whether a purchase order (or any kind of firm replenishment element) for that component already exists. If found, the CMC uses the availability date of that order (the latest date of all orders found). If no order is available, the CMC looks for a PO info record and uses the "worst" replenishment lead time it finds. If no info record is found, the CMC looks at the material master record and uses the "worst" lead time found there.
