I want to translate quantity error message. 
I changed in
app/design/frontend/Smartwave/porto/i18n/fi_FI.csv
"We don't have as many ""%1"" as you requested.","Meillä ei ole pyytämääsi määrää tuotetta ""%1"".",module,Magento_CatalogInventory and run php bin/magento setup:static-content:deploy fi_FI command but it's not working
There was the same msg in the fi_Fi.csv which contain the translation in English language only. So I just removed that line from the file.
When you do translation you don't need to pass ""%1"".
example :
"Get %1 off","obtenez %1 de réduction" - this will be you CSV file in you PHTML file you should have :
$discount = $block->getDiscount(); - if your using block $discount = $viewModel->getDiscount(); - if you are using view model <?= __("Get %1 off", $discount) ?> Try following way..
"We don't have as many ""%1"" as you requested.","Meillä ei ole pyytämääsi määrää tuotetta ""%1""." i have above code translate in fr langugage this work good for me
"We don't have as many ""%1"" as you requested.","Nous ne possédons pas suffisament de ""%1"" pour honorer votre demande." Note: Clear cache (php bin/magento cache:clean) and check your changes.
