Dear All, I am trying to upload the database from excel file to KOHA below are the list of fields available in the excel sheet and the corresponding MARC tags code. But when I upload the data to the KOHA using MarcEdit Software, as there is multiple copies of single ISBN number, I have used the matching rules (ISBN as unique identifier) and it had successfully matched the record and displayed the record number wherever there is a matching of records (biblio number). Database is successfully created message comes and display the biblio number. But when I do OPAC search it display two option. Error 1: Copies does not exit Error 2: Copies available in (library branch name) but when I try to Place Hold, it shows copies not available or missing.
