[Koha] question about database fields

[Linda Culberson]

In the wiki at 
http://wiki.koha-community.org/wiki/Holdings_data_fields_%289xx%29 it says:
"The connection between the marc field and the sql tables 'items' is 
done with the frameworks. You can't change the sql table 'items' but YOU 
can change the marc field and subfields."
However, we have found that the size for itemcallnumber is too small for 
some of our call numbers.  Does this mean that we cannot increase the 
size of the field?

Thanks in advance.
