Introduction
Overlapping Manufacturing Orders are similar to Overlapping Operations in the sense that they allow successor processes to begin before the predecessor has completed its run. In the case of Manufacturing Orders, the overlap is dictated almost entirely by the material availability and when those products and materials are considered to be available. Overlapping Manufacturing Orders must have a successor and predecessor relationship established in order to take effect. The products of one Manufacturing Order are then consumed as stock material in the successor Manufacturing Order.
Key Concepts
As mentioned earlier, the Manufacturing Orders in question must be linked by a predecessor/successor relationship in order for Overlap to occur. Whereas Overlapping Operations can be based either on transfer quantity or a time span, Overlapping Manufacturing Orders depend on the availability of the material being produced by the predecessor Manufacturing Order. For that reason, the Product being produced by the predecessor Manufacturing Order’s specific Operation sets when that product is considered to be available. The Product’s availability in inventory can be set by the “InventoryAvailableTiming” field. Its options are below:
At Operation Run Start: This option sets APS to assume that the Total Output Quantity of the Operation’s Products is available at the very beginning of that Operation’s run time. Using this option will allow the successor Manufacturing Order complete overlap beginning at this Operation.
At Material Post-Processing End: The Operation’s Run and Material Post-Processing times must all elapse before the Product is considered available in Inventory.
Based on Item Transfer Quantity: Similar to the Transfer Quantity in Overlapping Operations, this option specifies a Transfer Quantity that once reached will set the Product to be Available in Inventory.
