Hello,
There appears to be a bug with reports.
When I compare the same data in a report in different versions of Hikashop I get different results.

In versions of Hikashop 4.0.3 and above when making a PRODUCT report and selecting:
Specific Options:
Displayed Information: Sales / Orders / Click

Selecting option 'Order' now shows something different to the previous versions of Hikashop.
In version 4.0.2 and below the result was total number of products across all orders in the date range
In version 4.0.3 + the result is now appears to be number of Orders the product was in across all orders in the date range.

Is this a bug or a change?
We really need to display total number of products across all orders as in V4.0.2

Additionally, when clicking on a product in the results we are taken to a blank product page.

Please advise

Yes - I will have to install the latest version in our testing site as we have already reverted to V4.0.2
Will do this in the next day or so.

Screen shots as requested.
Please note - there is one customisation to show PRODUCT CODE rather than NAME - this is why the products have different names in the screen grabs.

Thank you.

Thank you Nicolas for the fast response!
