You must explode the production demands calculated in the operations plan to the supply sites that will manufacture or purchase the items.

Explosion Calculation shows the explosion calculation. For most items, the explosion creates firm planned orders for the production due quantities in the operations plan.

For co-product and by-product items, the explosion creates batch work orders (Status B) for the base process. The explosion does not create work orders for co-products or by-products. When you change the work order status from B to F, the system generates firm planned work order sets for the co-products and by-products associated with the base process.

Outside of the Enterprise Operations Plan module, these orders have the status firm planned. The system distinguishes operations plan orders from other orders by a special remark (OpsPlan). In form and function, these orders resemble master schedule orders.

However, within the Enterprise Operations Plan module, these orders behave more like MRP planned orders—that is, subsequent operations plan explosions will still add, delete, or change them.

The explosion assigns the orders to the supply sites designated in the item source matrix. It sets order due dates to the Monday of the week. It calculates release dates by offsetting item lead times from the due date.
