PST field has duplicate subfields 3, 4, 5, and 6

• Article Type: General

Description:
The version 18 loc/pst expands are not behaving properly:

PST0 L $$0Z30$$1000000501000010$$bOLSMN$$cCIRCB$$oBOOK$$d01$$fN$$rOLS60-000000501$$n0$$hPR468.I49$$iD38 1995$$aNUttSy$$3Book$$4OLIS Training Database$$5Circulating Collection$$6Regular Loan$$3Book$$4OLIS Training Database$$5Circulating Collection$$6Regular Loan
LOC0 L $$bOLSMN$$cCIRCB$$oBOOK$$hPR468.I49$$iD38 1995$$3Book$$4OLIS Training Database$$5Circulating Collection$$6Regular Loan
SBL L $$aOLSMN

Note that PST0 is repeating data.

Tab_expand for U39-DOC looks like this:
U39-DOC expand_doc_bib_loc_1_a
U39-DOC expand_doc_bib_loc_1_b
U39-DOC expand_doc_bib_loc_1_c
U39-DOC expand_doc_sort_loc_b
U39-DOC expand_doc_bib_loc_2_a
U39-DOC expand_doc_bib_loc_3_a
! 4_a creates LOC field
U39-DOC expand_doc_bib_loc_4_a
!U39-DOC expand_doc_hol_852_disp
!U39-DOC expand_doc_bib_hol_usm
U39-DOC expand_doc_bib_loc_usm
!U39-DOC expand_doc_bib_loc_4_a
U39-DOC expand_doc_bib_loc_cleanup

Resolution:
Deleting the U39-DOC expand_doc_bib_loc_usm" line corrected this problem.

Though it would seem that including this should not cause duplication of subfields, this line is not necessary here -- or in any other tab_expand section....

When you are using the expand_doc_bib_loc_n_x lines to generate the PST, and including expand_doc_bib_loc_4_a, the latter will produce a LOC field -- so expand_doc_bib_loc_usm is unnecessary.
