[Koha] [Koha-devel] bug in Acquisition module, regarding VAT management ?

[Fischer, Katrin]

Hi Mathieu,

 

from your description it looks like a bug to me too. I think what we need is documentation how each price element should be calculated for each vendor setting.  I often wonder – is it really a bug or is it miscalculation on my part?

 

Thank you for taking the time to document this!

 

Katrin

Hello
We think we have found a bug in Acquisition module, regarding VAT management, but we want to be sure.

Let's take a book whose recommended retail price excluding tax is 39 euros.
On the vendor's website, I import the record for this book in iso2709
In the record (UNIMARC), the price is in 010$d after the ISBN. So, I found : $d39.00 EUR
I stage this record in Koha with Stage Marc Records Tools.

In Acquisition module, I create a vendor with:
- List item price includes tax: Yes
- Invoice item price includes tax: Yes
- Discount: 9.0000 %
- Tax rate: 5.5%

I create a new basket for this vendor.
I fill this basket with my stage record.

I think I should have for the command line in this basket : 
- RRP tax included : 39 euros
- Ecost tax included : 39 euros - 3,51 euros = 35,49 euros
- RRP tax excluded : 39*100/105.5 = 36,96 euros
- Ecost tax excluded : 35,49*100/105.5 = 33,63 euros

BUT instead I see the following values : 
- RRP tax included : 42.86 euros
- Ecost tax included : 39 euros
- RRP tax excluded : 40,63
- Ecost tax excluded : 36,97

So, Koha considered the "39 euros" value in my record as a Ecost price. I dont think it is normal, as as chose "List item price includes tax: Yes" in vendor record.
Do you agree with me?
