How automatic warehousing helps with receipting stock for sales back orders

When the purchase receipt is posted, automatic warehousing will release shipments for any sales orders that now have sufficient stock. Those will, in most cases, be sale shipments for back orders. 

There will be a short delay after you finish posting the receipt, giving automatic warehousing time to release any required sale shipments. Then pick the sale shipments directly from the pallet's of stock you have just received.

Once all the back orders have been picked, put away any remaining stock into the warehouse.

Make sure you follow this approach. Otherwise you may end up putting the stock way into the warehouse only to then have to go and pick the same stock again in order to supply sales back order shipments.
