Title: Eric CAUDAL
As far as I have experienced due to business constraints, you can have different precisions for sales prices, purchases prices and accounting.

I have a customer who is selling small pieces at for example 0,123 RMB each (in RMB) and buy it at 0,1234 (in euro). You dont want your accounting to be impacted because usually these are total numbers (you keep it at 2 digits).

The factor between euro and RMB is small (x10) but some other currency have larger proportion (I am thinking for example in Vietnam dong)

It will depend a lot on business conditions, which is very difficult to foresee. This is why I tend to advocate for a common sales price precision for SO and CI, a common purchase price precision for PO and SI and a separate accounting precision.

To be noted that this is not what this module is doing: it creates only a accounting line precision: to achieve sales price precision different to purchase price precision, we should create in the invoice line 2 different prices (one for sales and one for purchase) and change all internal calculations. For simplicity (and because I didnot need it) I kept it as a separate precision.

Thanks for you input Eric.
I agree that the precision must be the same in invoices and orders. 
If I understand, you propose to "push" the order's precision to the invoices and accounting entries.
Isn't it simpler to just set the order lines' precision to that of the accounting?

** Summary changed:

- Wrong precision for tax  in sale/purchase order lines
+ Wrong precision for subtotals  in sale/purchase order lines
