From: Jason Etheridge Date: Fri, 28 May 2021 20:25:22 +0000 (-0400) Subject: lp1905028 lost items and price versus acq cost X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=aaad4807a982edfe968585e6398906dccde4cfde;p=evergreen%2Fpines.git lp1905028 lost items and price versus acq cost This feature adds two new library settings: Use Item Price or Cost as Primary Item Value Use Item Price or Cost as Backup Item Value which intersect the behavior of these existing settings: Charge lost on zero Default Item Price Minimum Item Price Maximum Item Price Each of these settings affect how item price is used in various contexts and is not limited to "lost" items, but can affect notices, fine rules, and billings for long overdue and damaged items (as well as lost items). By default, the price field on items is the only field considered by these various uses, but if we set, for example, "Use Item Price or Cost as Primary Item Value" to "cost", then we'll use the cost field instead of the price field. Alternately, if we set the "Backup Item Value" to "cost" and either leave the "Primary Item Value" setting unset or set to "price", then we'll consider the price field first, and if it is either unset/null or equal to 0 (and "Charge lost on zero" is true), then it'll fall-through to the cost field. We can also flip the behavior with these settings and consider cost first and then price second.
