Purchase Export BC Module This plan covers the implementation of the "export PO to BC Format" feature for Odoo 19, added as a custom module.

purchase_export_bc (New Module) Module Structure:

• init.py and manifest.py: Describe the new module and its dependency on purchase.
• models/init.py and models/purchase_order.py: Extend the purchase.order model by adding the "action_export_bc" method. This method will filter order_line, group them by the product's category name (product_id.categ_id.name), create a new sheet per category, evaluate x_studio_bc_item_id and the units/packaging, generate the Excel document using xlsxwriter, and return an ir.actions.act_url to download it.
• views/purchase_order_views.xml: Extend purchase.view_purchase_order_form to inject a new button "action_export_bc" into the existing .
