Before this commit the reports in sales and associated app suffered from a confusion between multiplicative and divisive rates for currency conversion. After this commit this will no longer be the case. There are several models with their own currencies that are involved in computing the amount of a sale order: - the order's company currency `order.company_id.currency_id` - the order's pricelist currency `order.pricelist_id.currency_id` - the product's currency for each product in the sale order `product.currency_id` In the case of a report we need also to take into account the current user's company currency: `self.env.company.currency_id`. The `sale_order.currency_rate` is the **multiplicative <u>rate</u>** to convert from the company currency into the SO currency. Any product added to a sale order follow the next conversion. Let `conversion_rate` be the conversion rate between the product's currency and the order's company currency, then: ```python product_amount_converted = product.list_price / conversion_rate order.amount_total += product_amount_converted * order.currency_rate ``` The rates returned by `_get_query_currency_table()`, on the other hand, are computed as the **multiplicative <u>ratio</u>** to convert from each company currency into the current user's company currency. Any order that is to be analysed on a *report* follow the next conversion. Let `current_company_currency_rate` be the conversion rate between the order's company currency and the current user's company, then: ```python order_amount_in_cmp_currency = order.amount_total / order.currency_rate report.order_id.price_total = order_amount_in_cmp_currency * current_company_currency_rate ``` What follow is a numerical example. Suppose you have the following multi-company and multi-currency environment. |order.id|order.company |line.subtotal|order.currency|order.currency_rate| | ------ | ----------- | ----------- | ------------ | ----------------- | |1 |BE Company (EUR)|1000 |INR |89.46 | |2 |BE Company (EUR)|2000 |USD |1.09 | |3 |BE Company (EUR)|3000 |EUR |1.0 | |4 |US Company (USD)|4000 |USD |1.0 | If we try to convert all of this for reporting in the US company, the currency table returned by `_get_query_currency_table()` will give this (company currencies vs USD): |currency_table.company|currency_table.rate| | -------------------- | ------------------ | |BE Company (EUR) |1.09 | |US Company (USD) |1.0 | Finally, in order to convert each amount into USD, applying the formulae listed above should give the following result: |order.id|order.company|display_price_usd | | ------ | ----------- | -------------------------- | |1 |BE Company |1000 / 89.46 * 1.09 = 12.18 | |2 |BE Company |2000 / 1.09 * 1.09 = 2000.00| |3 |BE Company |3000 / 1.0 * 1.09 = 3270.00 | |4 |US Company |4000 / 1.0 * 1.0 = 4000.00 | |Total (USD): 9282.18| Task - 3277006 closes odoo/odoo#125402 X-original-commit: e8f7a692eaf6b87ccf4a8d95b7a46146b1199bf2 Signed-off-by: Victor Feyens (vfe) <vfe@odoo.com> Signed-off-by: Horacio Tellez Perez (hote) <hote@odoo.com>
