[Koha] Sorting conundrum

[Doug Dearden]

Hello all,

I have a database that has no item records, only biblios.  We are using it to catalog some archival folders, and pointing to pdfs with scanned images using the 856u field.  We are using the 099a field as the call number field.  In Administration - System Preferences - Cataloging - Record Structure - itemcallnumber we have 099a filled in.  I just changed the Koha to MARC mapping so that items - itemcallnumber maps to 099a .  After doing a search the results page is sorted in Relevance order.  Changing the sort order to Call Number order, either Z-A or A-Z does not produce any change.  Changing the sort order to Title or Author works.  How do I get the sort working using the Call Number in the 099a field?

Thanks,
