Hi, All -- We're part of a 3-library coop where patrons have reciprocal borrowing privileges at any of the 3 libraries. Ideally, I'd like to be able to generate summary statistics on how patrons from each library are using these privileges, based on patrons' home library, the owner of items checked out, & where the transaction physically took place. I expected the following report to do this for me: SELECT s.datetime, i.itemcallnumber, i.itype, i.ccode, i.barcode, b.categorycode, s.type, b.cardnumber, s.branch, b.branchcode, i.homebranch FROM statistics s LEFT JOIN items i on (i.itemnumber = s.itemnumber) LEFT JOIN borrowers b ON (s.borrowernumber = b.borrowernumber) WHERE s.type in ('issue','renew','localuse') AND s.datetime BETWEEN <<Between (yyyy-mm-dd)>> AND <<and (yyyy-mm-dd)>> ORDER BY i.itype, i.ccode, i.cn_sort asc Unfortunately, for 17% of the transactions the home library of the patron is missing (b.branchcode). In our case, this amounts to some 33,000 transactions for 2013. The vast majority of these transactions (98%) are of type Local Use. (We have the RecordLocalUseOnReturn preference set to 'Record' for when items not checked out are checked in.) Can anyone explain what's going on here? Does it have something to do with how Transfers between branches are recorded by Koha? Thanks for any insight you can offer. Best, Cab Vinton, Director Plaistow Public Library Plaistow, NH
