Features

• New model sale.order.line.kit (inherits sale.order.line) that stores the exploded component lines, linked back to the parent SO line via sale_line_id.
• New one2many kit_line_ids on both sale.order (all kit lines of the order) and sale.order.line (kit lines for that SO line).
• Automatic explosion on create and on write for orders in draft or sent state: generate_sale_order_line_kit re-creates the kit lines from product.product.kit whenever the order lines change.
• Per-component pricing through the order's pricelist, partner, currency, UoM and date — taxes are recomputed via tax_ids.compute_all so price_tax, price_subtotal and price_total are kept consistent on each kit line.
• Parent SO line price_unit is recomputed from the sum of the kit lines' subtotals through get_sale_kit_price, so the customer sees the kit as a single priced line.
• Recursion guard via the change_from_soline context key avoids loops between parent and kit line writes.
• Orphan-line cleanup: stale sale.order.line.kit rows whose sale_line_id was reset by a one2many replace are unlinked automatically on write.
• Dedicated Kit Order Lines tab on the sale order form, grouped by SO line, with editable quantities, prices, taxes and UoM.
• Cascade unlink from sale.order.line cleans the related kit lines; _check_line_unlink is overridden so kit rows are always deletable.
• product_document_ids and invoice_lines are mirrored on kit lines for document attachments and invoicing hooks.

Configuration

There is no dedicated configuration screen — the module activates itself as soon as kit data exists on the products you sell.

1. Prepare the kit catalog

1. Configure the kit product and its components in the base module:
   • Tick Is a Kit Component on each component at Sales → Products → Products.
   • Open the kit product and fill the Kit Products tab. See the nexterp_product_kit documentation for the full setup.

2. Pricelist and taxes

1. Make sure each component product has the correct entries in any Sales → Configuration → Pricelists that you use, because the explosion prices each kit line through the order's pricelist (not from the parent SO line).
2. Set taxes (tax_ids) on the kit product as usual — the parent SO line copies them to every generated kit line.

3. Access rights

The sale.order.line.kit model is delivered with its own ir.model.access.csv entry. Users who already have access to sale orders (Salesperson / Sales Manager) automatically see and edit the Kit Order Lines tab.

4. Sale order form

No further configuration is needed. The Kit Order Lines tab is appended automatically to the standard sale order form (sale.view_order_form). The tab is grouped by parent SO line and becomes read-only once the order is cancelled or locked.

To install this module, you need to:

• clone the branch 16.0 of the repository https://github.com/NextERP-Romania/odoo-community
• add the path to this repository in your configuration (addons-path)
• update the module list
• search for "NextERP - Product Kit Sale" in your addons
• install the module

How it works

Adding a kit to a quotation

1. Open Sales → Orders → Quotations and create a quotation.
2. On the Order Lines tab, add a line with a kit product (any product that has entries in its Kit Products tab).
3. Save the order. The module reads product.product.kit and automatically creates one sale.order.line.kit per component under the new Kit Order Lines tab, with:
   • Sale Order Line — back-pointer to the parent SO line.
   • Product — the component product.
   • Quantity — parent_qty * kit_line.product_qty, converted through the parent's UoM.
   • Unit Price — taken from the component's contextual price (pricelist, partner, date, UoM).
   • Tax — copied from the parent SO line and recomputed.
   • Subtotal — recomputed via tax_ids.compute_all.

Adjusting a kit on the order

• Kit Order Lines tab is editable: change quantities, prices, discounts, taxes or even the component product on a kit row.
• The parent SO line's Unit Price is recomputed automatically from sum(kit_lines.price_subtotal) / parent.product_uom_qty, so the customer-facing total stays in sync.
• Changing the parent SO line (product, quantity, taxes) re-explodes the kit lines on save: the existing kit rows are unlinked and a fresh set is generated from the kit definition.
• Removing the parent SO line cascades and removes its kit lines.

Pricelist behaviour

Each kit line is priced through the order's pricelist using the component's own UoM and quantity. Switching the order's pricelist re-prices each kit line on the next save; promotions or quantity-based rules on the component product apply directly.

Limitations

• Re-explosion only runs while the order is in draft or sent. On confirmed / locked orders, kit lines can still be edited individually but the standard order line will not regenerate them.
• Kit lines are reference rows for pricing and reporting; they do not produce their own delivery or invoice unless other modules hook into sale.order.line.kit (e.g. nexterp_product_kit_sale_timesheet for tasks).
