Assemblies to trigger Production and Purchase Orders

Currently if I am unable to complete an Assembly no backorder is triggered for any missing components. This means I have to manually start the required production order. When products are out of stock on a sales order they are backordered however this does not happen during an Assembly, it creates a gap in our work processes.

If an auto assembly is backordered it creates an assembly order in draft. I am happy to then manually authorise this order. However at this point it would make sense that any products out of stock either create a production order (if product has a production BOM) or purchase order.

I make use of many nested production BOMs but they always require manual intervention to start the production orders needed for an assembly.
