Subject: Add "Last circulation date" field to new rcl view
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=447e0d800963a1e64845adecbc7a09e9fc1a96c4;p=evergreen%2Fpines.git

Add "Last circulation date" field to new rcl view

Some libraries will want the option of filtering out copies which have
truly never circulated, so offering up the bare "last circulation date"
field rather than coalescing it with "create date" will give report
writers the ability to use an IS NOT NULL clause.
