Preactor Express offers an unlimited number of resources, products and operations within a schedule.  Additional fields are also available for holding order and operation attributes.

It has an Excel spreadsheet Import for orders, products, resources, and resource groups.  Schedule information can be exported via the inbuilt reports.

There is a Capable to Promise enquiry button by which an test order can be added to the existing schedule to find an achievable delivery date.  The product, quantity and earliest start date can be entered and Preactor will automatically explode the order into the process steps and forward sequence these to find the earliest completion time without altering existing orders.
