Comment 14 for bug 1731042

Here is a stab at a fix for this by Jessica Woolford and I - with much thanks to the New Developers Working Group and Elaine Hardy for talking through the different workflows and settings!

https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/mccanna/lp1786971-z3950-bibid-tcn-3

To test:

1. In Administration > Server Administration > Global Flags: Set cat.bib.use_id_for_tcn to No (we need to do this in order to be able to import a new record that has a TCN that does not match the Bib ID).
2. Go to Cataloging > Import Record from Z39.50
3. Do a Library of Congress or OCLC search for Gone Girl, select a record and import it
4. Go to the record and verify that the TCN and Bib ID are different from each other (also, verify that the tab now says "TCN" and not "Bib" and that the number displayed matches the TCN).
5. Click Mark For > Overlay Target
6. Go back to Cataloging > Import Record from Z39.50
7. Note that the screen now displays the TCN as well as the record number - eg, "Record 258 marked for overlay (TCN 18120438)"
