-------------------------- - REPLICATING THIS ISSUE - -------------------------- If we had a biblio, with 4 items, each being issued 50 times. Running the update_totalissues.pl in stats or items -mode would yield a biblioitems.totalissues value of 200. If we get rid of one of the books, and recalculate, the biblioitems.totalissues value will drop to 150! update_totalissues.pl works in incremental mode, but a recalculation will ignore deleted items.
Since statistics contains only itemnumber, once item deleted we can not link this itemnumber to its biblionumber.
