When creating an invoice you can create it without a billing or shipment date You can then alter the shipment cost, however, trying to define a billing date without first defining a shipment date causes: invoice.pl: Odd number of elements in hash assignment at /home/vagrant/kohaclone/C4/Acquisition.pm line 2700., referer: http://localhost:8081/cgi-bin/koha/acqui/invoice.pl Define only a shipment date and the change will go through, but then attempting to change the shipment cost will fail until a billing date is also defined
I can't replicate this bug on current master. I've tried several things on the 'receive shipment' and on the 'invoice' pages, but weren't able to make Koha explode.
