[Koha] 003 field

We are having an issue when importing records using the z39.50 server. When can import, but when we go to save it says that there is an error because the 003 field is not filled in. 1: I thought that this normally was automatically filled in based on the 001 field. 2: In the "Books, Booklets, Workbooks" framework, this does not seem to be an issue, but if using the Default framework it is. Any ideas? Thanks, Kate Elliott Hopewell Public Library
