Purchase Line Subtotal Editable
Direct price_subtotal Control on Odoo 19 Purchase Order Lines
Directly edit price_subtotal on Odoo purchase order section & note lines. No quantity or unit price changes needed. Zero model changes. Pure XML view inheritance.
The Problem: Locked Subtotals on Odoo Purchase Order Lines
Every Odoo procurement team managing complex purchase orders, framework agreements,
blanket purchase orders, or vendor quotations has hit the same wall — the
price_subtotal field on Odoo purchase order lines is
locked by default and cannot be edited directly.
For standard product purchase lines, this is by design. But for section lines, note lines, and non-product display type lines, this restriction causes serious procurement workflow problems:
- Cannot display a custom grouped subtotal on a PO section line
- Forced to use reverse-engineered unit prices that confuse vendors
- RFQ processing slowed when vendor quotations include section-based pricing
- Framework agreements and blanket POs with category-level pricing require manual workarounds
- Multi-phase procurement documents cannot reflect phase-level purchase totals cleanly
- Odoo implementers spend hours on bespoke development just to unlock a single field
The Solution: Editable price_subtotal on PO Section & Note Lines
Purchase Line Subtotal Editable uses pure XML view inheritance to unlock
the price_subtotal field on all Odoo purchase order lines where
display_type is not a standard product line.
Once installed, every purchase order section line, note line, and text line has a fully
editable price_subtotal field.
Type the subtotal value. Save. Done.
Product purchase lines remain completely protected — Odoo's standard qty × price_unit calculation logic is 100% preserved on all product lines.
Key Features
- ✓ Direct price_subtotal Editing on PO Section Lines: Edit the subtotal directly on purchase order section lines, text lines, and note lines. No quantity manipulation. No unit price workarounds. Set the exact total your PO needs.
- ✓ Smart Locking — Product Lines Stay Read-Only: Standard product purchase lines remain fully auto-calculated and read-only. Only non-product display type lines are unlocked. Core PO calculation integrity preserved.
- ✓ Dual View Support — PO Form & PO Line Tree: Works on both the Purchase Order form view AND the standalone purchase order line tree view. Consistent behavior across all Odoo 19 purchase interfaces.
- ✓ Zero Model Changes — Pure XML View Inheritance: 100% XML view inheritance. No new database tables. No model overrides. No ORM changes. Fully upgrade-safe, conflict-resistant, and compliant with Odoo development best practices.
- ✓ Instant Activation — Zero Configuration: No settings to configure. No user access rights to modify. Install and the editable subtotal field is immediately live on all PO and RFQ line views.
- ✓ Non-Intrusive — Fully Compatible: Existing purchase orders, vendor pricelists, purchase approval workflows, budget controls, analytic accounting, and all purchase reporting are completely unaffected.
Real-World Use Cases
Framework Agreements & Blanket Purchase Orders
Set negotiated category-level subtotals directly on PO section lines to match agreed framework pricing — no quantity or unit price manipulation needed.
RFQ Processing with Vendor Section-Based Pricing
When vendors respond with section-based pricing or grouped line totals, enter quoted subtotals directly into PO section lines. Faster RFQ processing, cleaner documents.
Multi-Phase Procurement for Construction & Engineering
Reflect phase-level or milestone-level purchase totals on PO section lines. Clean, professional, vendor-ready multi-phase purchase orders.
Grouped Product Category Purchasing
Create clean POs with product categories as sections and set category-level subtotals directly. Ideal for indirect procurement, MRO purchasing, and capex PO management.
Consulting & Professional Services POs
Agencies, consultancies, and service businesses purchasing external services need section-based POs that reflect negotiated service area totals without unit price workarounds.

Technical Details
The module modifies the Odoo 19 purchase order line view using standard XML view
inheritance on the purchase.order.line model. The read-only attribute on the
price_subtotal field widget is conditionally removed — applying only
when the purchase order line display_type field is set (indicating a section,
note, or text line rather than a standard product line).
Dual View Inheritance Coverage:
- purchase.order form view — editable
price_subtotalon embedded PO line tree inside the purchase order form - purchase.order.line tree view — editable
price_subtotalon the standalone purchase order line list view
- No Python controller changes
- No JavaScript widget overrides
- No database migrations
- No performance impact
- No additional ORM queries
- No impact on purchase approval and budget workflows
- No interference with vendor pricelist calculations
- No conflict with analytic accounting integration

Frequently Asked Questions
Q: Does editing price_subtotal on a PO section line affect accounting entries or stock moves?
A: No. Purchase order section lines and note lines do not generate accounting journal entries or inventory stock moves. Editing their subtotal affects the displayed total only.
Q: Does this affect PO PDF reports?
A: Standard Odoo PO PDF report templates do not display section line subtotals by default. Most users will see no change in printed PO output unless using a custom report template.
Q: Compatible with Odoo Enterprise?
A: Yes. Works on both Odoo 19 Community and Enterprise editions, including Enterprise purchase approval workflows, purchase budgets, and analytic accounting.
Q: Does this affect vendor pricelist calculations?
A: No. Vendor pricelists and purchase price computation apply exclusively to product purchase lines. Section and note lines are outside pricelist logic entirely.
Q: Will this break after an Odoo 19 update?
A: The module uses stable, officially supported Odoo XML view inheritance APIs with no dependency on internal implementation details. Designed to survive standard Odoo 19 updates.
Q: Works with multi-company?
A: Yes. Applies globally across all companies in the Odoo 19 multi-company instance.
Q: What happens when the module is uninstalled?
A: The price_subtotal field on PO section and note lines returns to its default read-only state. No purchase order data is lost and no records are modified.
