Can you please provide a test plan for this?
We can't seem to save a record without field 942 filled anyway, so not sure when this bug would occur.
It is probably due to our Voyager-> Koha data migration pipeline. For performance reasons it skips the bulkmarcimport.pl -script. In Koha there probably are other points where the presence of field 942 is assumed. However having migrated a few libraries already, we don't seem to be facing any strange problems yet.
(In reply to Aleisha Amohia from comment #2) > Can you please provide a test plan for this? I cant remember how the stock Koha-Community version actually uses the biblio.serial -flag. We have a feature which paginates our 500+ (up to several thousand) serials and their attached records on the detail.pl to a serial enumeration tree: 2018 -> : 1 -> : 1 -> : 2 -> : 3 -> : 4 -> : 2 -> : 1 ... Then by clicking the enumeration component we render (from the REST API) all the Items matching that year/issue/volume. This way loading the detail.pl doesn't take up to one minute, but typically only seconds with large Item volumes. To activate the "dynamic Serial numbers tree" -view, we check the koha.biblio.serial -flag
Sorry, does not apply, please rebase.
