Will fix: Batch deletion failed: Cannot enqueue this job. (The error was: Can't use string ("on") as an ARRAY ref while "strict refs" in use at /kohadevbox/koha/Koha/BackgroundJob/BatchDeleteItem.pm line 214. , see the Koha log file for more information).

|
|
|
|
Will delete all the items that have been passed for deletion.
|
|
|
|
When deleted_biblios is passed, if we deleted the last item of a biblio,
|
|
the bibliographic record will be deleted as well.
|
|
|
|
The search engine's index will be updated according to the changes made
|
|
to the deleted bibliographic recods.
|
|
|
|
The generated report will be:
|
|
{
|
|
deleted_itemnumbers => \@list_of_itemnumbers,
|
|
not_deleted_itemnumbers => \@list_of_itemnumbers,
|
