[Koha] Unexpected behaviour 942 $h (3.18)

[Elaine Bradtke]

I am a bit embarrassed.
After discussing this problem with my IT wizard who actually looked at
callnumber.pl and understood it's inner workings, I know where the unwanted
numbers are coming from.  Many of our call numbers consist of nothing more
than two upper case letters, for example QM. The plugin is looking at that
and seeing a prefix and adding sequential numbers to create a unique call
number. Our numbers are not unique.

Perhaps a brief explanation of what this plugin is meant to do would be a
useful addition to the manual?
As I understand it, the plugin looks for any number of or combination of
upper case letters, and/or punctuation.
It treats that information as a prefix, chooses the largest number assigned
to this prefix, and adds one to it. If there is no number it adds a space
and a number 1 to the end.
For example If I type in M, it looks for all the Ms in the call number
field, finds the one with the highest number and then adds the next number
in the sequence (for example M 123 exists, so it will make this one M 124).

Unfortunately that won't work with our system.  But at least I know I'm not
going mad.
