[Koha-devel] Discussion: how to tackle a problem with statistics data

[Tomas Cohen Arazi]

A customer found a problem with statistical reports. They found the
circulation stats for returns grouped all returns on the NULL itemtype.
What? Well, yes.

My first idea was to fill a bug for that [1]. But looking for the bug on
the reports code, I found that the problem was in C4::Circulation. So
filled a bug for it [2] and provided regression tests and the fix. Cool.

But what about the wrong data on the statistics table? Basically, all
returns have the wrong itemtype (NULL). Should we fix that table's data?
Should we make the report do the proper JOIN operation on the items table?
I'd go with the first option, but probably worth discussing, because there
are other bugs related to how the 'statistics' table have been filled. [3]
