I do batch loads of records into our Koha system. Some records are new and some are for overlaying (and updating) existing records. The load process generally gives me a notice that there were no overlays. Even though the "Match Details" area says that there are matches. So, I reverse the load and try again. The second try finds the matched records and everything is fine. But, why does it take two tries? I did a load today. The screenshot of the first attempt is at: http://www.andrews.edu/library/Nomatch.jpg Note that the screenshot shows: 1) Staged session with date and time, 2) A match rule has been applied, 3) Replace existing record with incoming, 4) Records added is 4609, (no overlays) 5) Match type says "Match Found", 6) There are matches in the Match Details. After reversing that load I try again and it is fine. The screenshot is at http://www.andrews.edu/library/Matchafterreverse.jpg Note: 1) Same staged session as before, 2) Same match rule, 3) Still replacing matches records with incoming, 4) Records added is 661 and records updated is 3948 (i.e. matched), 5) Match type says "Match applied", 6) Matches in the "Match details". Why does Koha need two tries when it knows that there are matches? Is this a bug that needs to be fixed? I have seen this behavior with loads as small as 200 records. Koha version: 3.18.06.000 Original version was installed by an "automatic" process that our IT gurus found. Updates since then are done "automatically" when a clean update is available.
