When a supply chain order is received, the pre-allocation is transformed into an allocation. The type of allocation is defined on 'Supply Chain Policy. Open' (CRS709) or on Item/Warehouse (MMS002/G). This allocation is used if a regeneration or a quantity change of the supply chain occurs.
The supply chain is not triggered by reporting. That is, if reporting 95 (including the finish mark), the supply chain demand is still 100, but only 95 is allocated to stock. The MRP takes care of the remaining 5, but a manual pre-allocation must be performed. The exception to this is when the upstream changes of a supply chain have been activated on the supply chain policy, as described in the section ‘Upstream Changes of a Supply Chain’.
The supported scenarios are:
