Call number not displaying in Course Doc List

In the Circ module, Course Reserves, the call number frequently does not show up in the in Course Doc List. We have the call number coming from LOC## h in tab22.
Also, despite the fact that we have the following line in the abc30 tab_expand:
most xxx30 records do *not* display the LOC field in util/f/4.
The bib data displayed in the Course Doc List comes from the z13 record. In your case we are seeing that the z13_call_no is blank. This is the result of the CREATE-Z13 lines in the abc30 tab_expand. You have:
The expand_doc_bib_loc_usm works only for records whose xxx30 doc is linked to the item via a (z103) ADM-type link; it does not work for ITM-type links:
the xxx30 professors' copies which are linked to the xxx50 item directly have a z103_lkr_type ADM;
the xxx30 records which are linked to the xxx50 item via an xxx01 bib record have a z103_lkr_type ITM.
As shown in KB 4022, expand_doc_bib_loc_usm is a hard-coded set of calls to expand_doc_bib_loc_n_x programs.
expand_doc_bib_loc_1_b reads items linked via an ADM-type link;
expand_doc_bib_loc_1_b2 reads items linked via an ITM-type link.
expand_doc_bib_loc_1_b2 is not one of the programs called by expand_doc_bib_loc_usm.
In order to include both LKR types (ADM and ITM), the xxx30 tab_expand needs to specify both _b and _b2:
Note: the expand_doc_bib_loc_4_a is necessary only if you are using the LOC field; it may be omitted if you are specifying "PST" as the field.
Other xxx30 indexes on call numbers may also need to have the relevant section of tab_expand changed (to include these expand_doc_bib_loc_n_x lines instead of expand_doc_bib_loc_usm) and the index regenerated.
Note that when you change tab_expand you need to restart ue_01, pc_server, and www_server.
