The way that you extract call number fields from Millennium/Sierra impacts how the call number type and $h and $i fields of the 852 in the holdings record in Alma are represented. You have the option of delivering call numbers from either the item record or the bib record (or both) and you can still retain the $h and $i subfields of the call number field. There are a couple of different ways to export item and bib record call numbers from your Millennium/Sierra system, and you will need to do one of the following if you want to ensure that all call numbers are migrated as specifiedwith the expected call number type and cutter.
In order for call numbers to migrate to the subfields $h and $i in the holdings record, you must export your item and/or bib record call numbers based on the MARC tag of the call number field. Both the item call number MARC fields and the bib record call number MARC fields can be included in your item record export CSV file. If you only use call numbers from the item record, then you can simply export the MARC tags from the item call number fields. Subsequently if you only use call numbers from the bib record, you can simply export the MARC tags from the bib call number fields.
