The actions Edit, Duplicate, or Delete on the button "Actions" in the table of Items that appear when trying to add or edit an item are not working. The problem seems to be at Koha/Item.pm on function columns_to_st where not added to the array the value from itemnumber column, because that column exists on the database but not in the framework and is not a subfield as the other columns. And also on additem.pl at line 653 is called so at the line 652 exists but on the next line, the itemnumber is disappeared. I provide the test plan and the patch soon.
I can't reproduce this in 24.06.00.007
