Material allocations, delivery types, and work order (activity) status

The work order material resource lines are created when the work order or work order activity can have the following status:

For the To Warehouse delivery type, an available-to-promise check is carried out during the Planned status of the work order or the work order activity. If commitment is required during the planning phase, a warehouse order is created after the work order is planned, and the material resources are then allocated. If commitment is required if the work order status is Released, the warehousing procedure starts after the work order or the work order activity is released.

For the Via Purchase delivery type, a purchase order is created when the work order status or the work order activity status is Planned. If you release the work order or the work order activity, the warehousing procedure is started to issue the materials.
