| Summary | 0056612: Error in tax calculation |
| Description | I reproduced an order in livebuilds with 39 lines and an amount, when the 13% tax is applied, it is calculated wrong.
This is due to rounding.
Since if we take the 3 decimals the calculation is correct, but if we take 2, the calculation is wrong. |
| Steps To Reproduce | 1 - Configuration of the tax rate - (attached the image)
2 - Make 39 lines of different products, and then add the quantities and amounts I attach.
IMPORTANT: if any discount is applied, deactivate them, or make the amount of the line with the discount equal to the one I attach in the excel.
Then you can see that the total of the order is 24474.24
The tax shown in the pos is 21658.56
but if I calculate the 13% of the total it is 21658.6194
There is a difference of 5

| Proposed Solution | The problem is in this line when we calculate the getTaxeLine
OB.DEC.toNumber(amount.multiply(amount).divide(amount.add(taxAmount), 20, BigDecimal.prototype.ROUND_HALF_UP));

The current tax information is properly calculated based on your Tax Rate configuration.
See: https://wiki.openbravo.com/wiki/Tax_Rate#Tax [^]
"Document Tax Amount Calculation" which is the way how the tax amount is going to be calculated per each tax rate (or %). The options available are:
"Document based amount by rate", this option implies that the tax amount is going to be calculated as tax amount = (tax base amounts sum at the same rate * tax rate)
"Line base amount by rate", this option implies that the tax amount is going to be calculated by line as tax amount = (tax base amount line 1 * tax rate) + (tax base amount line 2 * tax rate) + ....+ (tax base amount line n + tax rate).
As the Tax Rate is configured with Document Tax Amount Calculation = Line base amount by rate, the tax is calculated per line, that is why it doesn't match with the tax calculated by document: https://docs.google.com/spreadsheets/d/1bV9AirYmu1i_5VfhhBLsy4AADDLjdJ6qN2_VVoWW0W8 [^]
In summary:
If you configure the Tax Rate as Document Tax Amount Calculation = Line base amount by rate you will get:
Total Gross Amount: 24474.24
Total Net Amount: 21658.56
Total Tax Amount: 2815.68
If you configure the Tax Rate as Document Tax Amount Calculation = Document base amount by rate you will get:
Total Gross Amount: 24474.24
Total Net Amount: 21658.62
Total Tax Amount: 2815.62 |
