Hi Mauro
The thing it's with duplicates of issue_id in tables issues and old_issues... I cant figure since then why the id from issues makes a little rollback on it's value resulting in duplicates and (of course, when returning a borrow) data loss...
Answering your questions: - koha version: 16.05.04.000 - there're no warnings there - intranet-error.log confirmed (after i found the logs) that were id duplicates
I shall say that i can't update koha version now because the one that was before me made some changes for the people here and he didn't document anything... and as far as now I couldnt establish all of them in order for an update, so its out of cuestion to me right now :/
So my need now becomes how could i solve this duplicates for bad increment/rollback of the issues_id
Maybe the following information will help you: https://wiki.koha-community.org/wiki/DBMS_auto_increment_fix Best wishes: micahel -- Geschäftsführer · Diplombibliothekar BBS, Informatiker eidg.
