You still can eliminate the link removing the 773 field.

I agree that this needs to be addressed. My library is now on 17.05 and the 17.05 manual still describes editing analytical records by using "Edit in Host" and "Delink" which disappeared in 16.11: https://koha-community.org/manual/17.05/html/06_cataloging.html?highlight=analytics#editing-analytics

I can confirm that the following process worked for me for withdrawing a volume linked to an analytical record:
1) Delete the 773 in the MARC record of the analytical (child) record. Result: the record no longer had an item attached.
2) Delete the bibliographic record that was the analytical (child) record. 
-- Repeat 1 & 2 for all child records attached to the host --
3) Go to the host record.
4) Delete the item.
5) Delete the record.

I may need to revise my last comment. The first pair of linked analytical records I was looking at did not have the "Edit in Host" or "Delink" links available in the Action dropdown menu on the Edit Items page. The second pair of linked analytical records I'm looking at now do offer these as options.

Perhaps there was something corrupt in the first pair of records I was looking at.

I can now confirm that in 17.05 when going to Edit Items in an analytical (child) record, the options available are: Edit in Host, Delink, and OPAC View. Selecting "Delink" removes the host item from the record.

Perhaps this is not a bug after all? Or perhaps a bug still exists in versions prior to 17.05? Or perhaps it exists when you've tried to manipulate the record in other ways while it was still linked? For example, attempting to delete the host item from the analytical (child) record by using "Delete all items" did not return an error, but the host item still appeared and the Actions menu did not have the Delink option.

Hoping this makes sense to others.
