Hello, I am able to solve the problem (thanks to Kaitrin) but i am not able to prevent it, how can i prevent "holding branch" getting null values at item table, i think this is happing to every new items created in the koha database. I am not a librarian myself, does this have to do how our librarian coleagues are creating the items, am i missing any configuration set up parameter? +----------------+---------+---------------+------------+ | itemcallnumber | barcode | holdingbranch | homebranch | +----------------+---------+---------------+------------+ | 9349/M | 9349/M | NULL | BACOSTA | | 23623/M | 23623/M | NULL | BACOSTA | | 23624/M | 23624/M | NULL | BACOSTA | | 23625/M | 23625/M | NULL | BACOSTA | | 23626/M | 23626/M | NULL | BACOSTA | | 23627/M | 23627/M | NULL | BACOSTA | | 23628/M | 23628/M | NULL | BACOSTA | | 23629/M | 23629/M | NULL | BACOSTA | | 23630/M | 23630/M | NULL | BACOSTA | | 23631/M | 23631/M | NULL | BACOSTA | +----------------+---------+---------------+------------+ Best regards, Paulo Neto DSIGA / DPGI Tel.
