I try to migrate data from WISIS to koha. In record matching rules, I was created rule for matching with callnumber (tag 080$a). The result is "no matching found" , even though a match exists. If anyone met this issue before, please help me to fix.
I think this would be better on the mailing list - in order for the matching to work, you need to set it up correctly and possibly have a search index on the field too. Please try asking on the mailing list and see if people can help you there. I'd include exactly how you set up the matching rule for people to help spot the issue.
