A planning concept in which planning data is handled in the form of orders. In order planning, supply is planned in the form of planned orders. LN takes into account the start and finish dates of individual planned orders. For production planning, this method considers all material and capacity requirements, as recorded in an item's BOM and routing. These planned orders can be firmed, confirmed and transferred into execution level orders (purchase, production and warehouse transfers). Transferring the planned order means: execution order gets created and planned order gets deleted. Identifier of planned order and execution order do not match, they are separate entities.
