Creating a new order before receiving an existing order can result in overstocking. A new feature in Version 8.5 allows you to set a field in the Vendor Editor to block the ability to create a new order if an existing order has not been received. The field allows you to set the number of open orders that can exist at the same time. For example, if you set the field to 1, only one open purchase order is allowed. The default is zero, which means there are no restrictions. For vendors like your primary pharmacy wholesaler, setting the field to 1 likely makes sense, while for vendors like Variety Distributors, where you have both regularly stocked items as well as seasonal orders, setting the field to 2 may make sense. The new feature can be overridden by a manager as well.
