Analytic Tag Dimension Sale Warning

This module connects the analytic tag dimension feature with sales. It makes sale order lines participate in the same dimension checks that already exist for other documents.

What changes for users:

• On a sale order line, when analytic tags are chosen, Odoo can now detect if two tags belong to the same analytic dimension.
• A warning appears while saving the sale order, helping users avoid mixing tags from the same dimension.
• The warning behaviour comes from the analytic_tag_dimension module; this module simply extends it to sale order lines.

The module touches the sale.order.line model by adding the analytic dimension line behaviour and pointing it to the analytic_tag_ids field. It also extends account.analytic.dimension so that sale.order.line is included in the list of models where dimensions are checked.

There are no new menus, buttons, or reports. The module installs automatically when both analytic_tag_dimension and sale are present. No other business rules, computations, or scheduled actions are added by this code.
