[Koha] Migrating from LibraryWorld to Koha - problem mapping item information

Greetings, The Royal Thimphu College is currently in the process of migrating to Koha. We currently use LibraryWorld and are attempting to upload our bibliographic and item information. The bib information comes across fine and the item information is also there, BUT none of the item information is mapping to the Koha item record. If someone else has had this problem and resolved it, I would be pleased to know how you handled this process. Many thanks, amrita Amrita McKinney Professor and Library Adviser Royal Thimphu College Post Box 1122 Ngabiphu Thimphu, Bhutan +975-17320091 amckinney@rtc.edu
