Hii Andreas Meer,

There are two ways to achieve this.
Way 1:From the UI side.

Step 1:Go to Settings->Translations->Import Translation.
Step 2:A pop-up will open. You have to set the languages and upload your updated PO file.
Make sure that the 'Overwrite Existing Terms' option is checked. 
Step 3:Upgrade your module by going to the app list.

Way 2:From command line:

After completing of importing process of the updated PO file, upgrade your module through the command line and add '--i18n-overwrite' command along with it.

->This will overwrite existing translation terms on updating a module or importing a CSV or a PO file.

In Odoo online it still does not work. Uploaded the de.po file, updated the accounts app - no changes show up.

This seems to still be an issue. Having the same trouble when trying to change translation for: l10n_din5008_document_title on odoo.sh
https://github\.com/odoo/odoo/blob/d748ca8708aa5d13737de9b78722b3755a6cdebc/addons/l10n_din5008_sale/models/sale\.py 

I\ think\ also\ here\ the\ issue\ ist\ that\ it's\ marked\ as\ a\ python\ code\ value\ in\ csv\ \(see\ last\ column:\ odoo\-python\): 
l10n_din5008_sale,code,addons/l10n_din5008_sale/models/sale.py,41,Sales Order,Verkaufsauftrag,odoo-python

Hi Andreas, 

generate the .pot file and overwrite the one in the module, the translation file will work in this case. 

If the term to be translated is not in the pot file, the translation is not supported.

Hi, has anyone solved the issue ? I tried today 03/06/2023 on https://runbot.odoo.com/  on both version CE and Enterprise and the issue is still there. The import of translation files is not working. 

Hi evrybody,

To confirm that  Import Translation does not work at all on Odoo 16 latest version (30 of March 2023) as pointed out by Andreas.

There is no way to update module translations.

Those process was quite easy on Odoo 15, never issued.

Could someone explain techical reasons for this issue?

Thank you

Hello

Thank you, but I know that. The problem is that the import does not work. Have selected the correct language, language code and that it should be overwritten.

No change.

Greetings andreas

1. locate from which view are those terms, locate it in views list in Settings part.

2. via "show metadata" of the view locate whole xml path, first part of the ID before dot is name of the module, 

3. export this module, translate and upload 

4. let me know if it worked :)
