Hi, We have encountered some cases where the calculated Total tax amount is wrong. It appears there is a standard process which added a “tax_round” line, for which an adjustment is done. Let’s take the case : For each line and for header : Total price line HT Tax rate TVA (calculated) Rounded TVA (2 digits) 118,13 20% 23,626 23,63 73,5 20% 14,7 14,7 219,38 20% 43,876 43,88 411,01 82,202 82,21 Header total price Tax rate TVA Rounded value 411,01 20% 82,202 82,2 The problem is that on the invoice, the adjustment seems to be done on the wrong way (adding one cent instead of subtracting it), and the result is wrong. Let’s see the invoice : Having a look on the database, we may have this issue on 2 columns (yellow ones) for which value is positive instead of negative. Here is an extarct of the tax-line table : Does anyone already had this issue ? What can we do ? Should I create a ticket on the support ? Thank you ALLIANCE V15.4 SU3
