Description:
Why does the link from the LOC field in full view not work (only MAB2 environment)

Resolution:
The field LOC is built by expanding Z30 data to the BIB record. There are some things you should know when dealing with the LOC field:

2. MAB customers sometimes experience problems since the order of subfields is different from USM. In USM subfield b is the sub-library, in MAB it is the collection. Therefore the link from the WWW OPAC full view to the holdings fails, since the system searches for a non-existing sub-library with the name of a collection.

Solution: Create another configuration table for the LOC field, where you change the subfields. In tab_expand change the line

WEB-FULL expand_doc_bib_z30 CONF=expand_doc_bib_z30_loc,TAG=LOC

to

WEB-FULL expand_doc_bib_z30 CONF=expand_doc_bib_z30_loc2,TAG=LOC

Now create this new configuration table expand_doc_bib_z30_loc2 by copying expand_doc_bib_z30_loc:

cp expand_doc_bib_z30_loc expand_doc_bib_z30_loc2
vi expand_doc_bib_z30_loc2

In the new configuration file exchange the subfields a and b:

# z30-sub-library b space N
# z30-collection a space N

Now the sublibrary will be expanded into subfield b, just as it is in USMARC. The link from full view to the holdings will now work.
