Subject: LP#1516022: new reporting source for hold/copy ratios
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=4c9f565570b8b8b3f3b8ad7d31a878afa498638c;p=evergreen%2Ftadl.git

LP#1516022: new reporting source for hold/copy ratios

This patch adds a new reporting source, "Hold/Copy Ratio per Bib
and Pickup Library (and Descendants)", that, for each bib
that has a hold request on it or any of its components,
calculates the following:

 - active holds at each OU (including the OU's descendants)
 - holdable copies at each OU (and its descendants)
 - the ratio of the above two counts
 - counts and ratio across the entire consortium

This work was sponsored by the Pennsylvania Integrated Library
System (PaILS).
