In Apps View, there is a point "Import Modules". If you click it you get this dialog:
The yellow note says: "you can only import data modules (.xml files and static assets)".
How can I do this?
I have made this failed test:
I have changed a setting (+86 into +81) in the german tax report (which is XML based) on the GUI.
Then I have downloaded the XML file which should be the base for this report:
https://github.com/odoo/odoo/blob/tmp.saas-18.1/addons/l10n_de/data/account_account_tags_data.xml
I saved it as "account_account_tags_data.xml" and ziped it.
I have uploaded the ZIP using this dialog. There was no error message.
But after reloading the tax report, the changed word is still changed.
So the upload of the original XML file have not resulted in overwriting my test change.
What is the correct way to do this?
