HRID handling in Inventory for Holdings records

• If Holdings is linked to an underlying MARC record
  • Map the HRID from the MARC 001

• If Holdings is loaded directly into Inventory and the HRID field is present in the incoming JSON data [no linked MARC record in SRS]
  • Retain that number as the HRID in Inventory
  • Do not add any prefix specified in Settings (library should have entered it in the incoming file if it was wanted)

• If Holdings is loaded directly into Inventory and the HRID is not present in the incoming JSON data [no linked MARC record in SRS]
  • Assign next FOLIO HRID based on the Holdings sequential number generator in Inventory and the starting number in Settings
  • Assign the Holdings prefix based on the optional prefix defined in Settings
  • Map that number to the HRID of the corresponding Holdings record

• Once assigned, HRID is not editable
