No, the article you point to is about valuation using FIFO and LIFO, not
about average price. In FIFO/LIFO, every transaction have impacts on the
cost of the product, which is quite different from the average price
method.

I would be interested to find articles that explicitly says what to do
when you send back products to suppliers with average price. I did not
find one. I checked my accounting book, they only talks about the
reception of products. I think it's important to find references that
explicitly explains the rules before doing any development on this; i
heard so much different things about average price that I prefer being
sure before integrating something.

[5.0] return products to supplier does not update price average

Bug description:

When returning products to a supplier, the average standard price should be updated using the price of the packing list which is returned.

For example :
1- We have 10 products with average price = 100
2- We receive 5 products with price = 80 --> average price is calculated as (10*100+5*80)/(10+5) = 93,33
3- We return 3 products from the last packing list (the one where products cost 80)
The new average price should be 
(93,33*15 - 3*80)/(15-3)=96,67

If the return is made directly from the stock and does not concern any incoming packing list, we do not update the average price.
