When porting the mass module to Odoo 18, it was decided to move the merge the mass module into the module donation_mass. The experience shows that the mass module is never used without the donation module and that users are always given the same access rights on the mass module and the donation module. One of the major advantage of this merge is that it allows to use the donation_type field on products to configure the mass products.
Once you have successfully migrated to Odoo 18, you can remove this module (make sure that none of your specific modules has a depenency on it).
auto_awesome What this module does
AI-generated from the code · Odoo 18.0This module is an empty placeholder kept only so existing databases can still install it. It adds no screens, no menus and no business features; it is meant to be uninstalled.
The module is described in its own summary as an empty module to uninstall. It contains no Python models, no data files and no views, so it does not create any new screen, menu, button, report or automatic behaviour in Odoo.
Its only declared dependency is account, which means it can only be installed in a database where the Accounting application is already present. Nothing else is added on top of that.
- No new fields, tables or records are created.
- No access rights, rules or scheduled actions are defined.
- No configuration settings or menus appear for the user.
Because the module is empty, installing it changes nothing visible in day-to-day work. Its purpose is purely technical: it exists so that databases that previously had this module installed can still load it, and so that any other module depending on it does not break. The recommended action is to uninstall it once you have confirmed that no other custom module still depends on it. After uninstalling, no data is lost, since the module never stored any data of its own.
