Hi, I'm from São Bernardo do Campo, SP, Brazil. We have been working with Koha since 2009, and we are currently using version 18.11 in Public and School Libraries. Due to COVID-19 our Libraries are closed. I am studying a way to batch change the returns / check-in in this period. Would just changing the database, just like the example below, solve? Example: UPDATE koha_biblio.issues SET date_due="2020-04-29 23:59:00", lastreneweddate="2020-04-15 15:01:00" WHERE date_due LIKE '%2020-03-17%' Would this change affect anything else?
