The first step is to specify the default (or starting) number of days a job is expected to take. Under "Setup", "System Settings", on the Orders1 tab, is the initial setting for the number of days an order is expected to take if no other parameters are specified for any of the properties of a particular job. This allows the lab to specify the "normal" number of days, and then only set additional parameters for exceptions to take:that rule. (In other words, if plastic jobs always take the default number of days, there is no need to set up specific rules for plastic). 
In this example, 3 days will be added to the date received for every order.

Under "Setup", "Date Wanted Setup", the lab can specify additional days by material, type of lens (semi-finished or finished), and by Rx within that material. For each material for which the lab wishes to add additional specify the number of days, a record similar to the following can be created:
In the above example, 1 day is added if the lens to be manufactured if a Semi-Finished Poly; an additional 2 days is added if a Poly job that used semi-finished blanks would take 3 days; a finished Poly lens only 2 days. If the lens is above a 6.00 sphere, or below a -8.00 sphere, or above a 4.00 cyl, above 5D of prism, or has an add of 3.75 or greater then it will be set to 4 days (not this is in lieu of the other days, not in addition to). AlsoHowever, an extra day is added if the job is to be edged and mounted (a complete job).
