Property in Account Move Budget

This module extends the accounting budget lines used by the Account Move Budget feature so that each line can be associated with a hotel or property.

• A new optional field called Hotel is added to budget lines. It links the line to a property record from the Property Management System.
• The Hotel column is shown in the budget lines list view, placed immediately after the partner column, so users can see and set the property directly from that screen.
• The field is not mandatory, so existing budget lines can remain without a hotel.
• The field is indexed, which helps when searching or filtering budget lines by hotel.

The module touches the account.move.budget.line model and the budget lines tree view. It does not add menus, buttons, reports, automatic checks, computed values, default values, emails or scheduled jobs. It only adds the property field and displays it in the existing budget lines list.
