[Koha] Zero padding callnumber

[Marcel de Rooy]

Hi all,
Does anyone of you have experience with zero padding callnumbers in Koha?
We have shelves like 1, 10, 100 and 1000. And reports are always
problematic since 10 is between 1 and 2, etc.
So we want to zero padd to 0001, 0010, 0100 and 1000.
Since we will not adjust older hand written labels on books, they will
still list 1, 10, 100, etc.

Searching for the older callnumbers will no longer work after renumbering.
(Unless we leave the old callnumber in the record too, or make Koha's
search a bit wiser somehow.)

If you did something similar, did you encounter other things to take into
account?

Thanks,
