https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=37375 --- Comment #17 from José Anjos <joseanjos@gmail.com> --- I agree with Lari Taskula suggestions. Meanwhile, this error forced me to review all the MARC mapping fields and tables. (No revision since 2003 ;) ) In addition to the location error, I also had this one: row._strings.collection_code is undefined Finally, it was resolved by associating the CCODE Authorized Value to 995$h (UNIMARC) I didn't test the Patch because I preferred to correct the fields to don't have problems in the future. However, I opened a new bug because there are differences in the UNIMARC fields from the documentation and the Wiki: https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=37772 Thank you all for your help. -- You are receiving this mail because: You are watching all bug changes.
