Hey thank you for your reply.

i found that module, and i try to install it, manually over file system and scan the addons folder in developer mode (doesnt show up) and with "import module" under apps settings in developer mode, the import gives an error ( i think, this module is not really compatible with my installation? ) i try to dig around that problem, maybe i can get this addon running and that would be my easiest solution i think.

Fehler beim Importieren des Moduls 'om_data_remove'.

 while parsing /tmp/tmpgc55s4so/om_data_remove/views/view.xml:4
Fehler bei der Validierung der Ansicht nahe:

                        Remove All
                        
                    
                    

                        Sale

remove_all ist keine gültige Aktion für res.config.settings

View error context:
{'file': '/tmp/tmpgc55s4so/om_data_remove/views/view.xml',
 'line': 13,
 'name': 'Remove Data',
 'view': ir.ui.view(2684,),
 'view.model': 'res.config.settings',
 'view.parent': ir.ui.view(),
 'xmlid': 'view_remove_data'}

maybe other persons have another solutions in this case? if i get it to work i will update the solution here :)

greetings

Hello,

You can check this free module (not mine): https://apps.odoo.com/apps/modules/17.0/om_data_remove

This should allow you to delete the test invoices, among others.

Edit (Update) check this demo:
