- If user enables automated linking for any 6XX then check against these subject thesaurus validation rules and presence of $0
- If $0 exist for an authority record and that authority record follows the defined tenant subject thesaurus validation rules then link the bib field
- If a single subfield 2 is used to link the bib field then the field should be read only
- If multiple subfield 2 then only keep the subfield 2 that is tied to the linked authority heading
Manual linking
- Apply validation rules
- If user creates a new field then
- Check 2nd indicator value for rules to apply
- IF 2nd indicator value = 7 then populate subfield 2 with authority field/subfield value defined by library Source code and make read only
- If invalid selection then show an error message [You have selected an invalid heading based on the bibliographic field you want controlled. Please revise your selection.]
