Alternate fields, Z13 fields in edit_doc_999 and www_tab_short

• Article Type: General

Description:
Is it possible to display Z13 fields, as defined in tab22, in the Web OPAC brief and/or full displays?
What I'm trying to do is to display the Call Number selectively,: If there is a Holdings record, display the Call Number from there, if not, display the 099 field. I was thinking of doing this using either the Z13_CALL_NO, or one of the Z13_USER_DEFINED fields, but can't find any documentation as to whether this is possible in edit_doc_999.eng.

Resolution:
It is not possible to display Z13 fields in either the Web Full or Brief displays.
In the case of the Brief display, the www_tab_short.eng has a "second field code" in which you can specify an alternative tag. Thus, you can have PST as the first field code and 099 as the second. If there is no PST, the 099 will be included as the z13_call_no.
edit_doc_999.eng does not have this alternate fields feature.
