How to dismantle a whole into partsكيفية تفكيك الكل إلى أجزاء

You bought a wrecked car front for 1,000 USD. A customer wants the headlight. You never bought a headlight, so there is nothing in stock to sell and nothing to cost it at.

Dismantling solves this: it is production run backwards - one raw material in, many products out - and it creates the parts as real stock with a real cost.

Before you start you need the advanced production tier, the one with a Percentage column. If your production invoice has no such column, stop here and ask your Libra provider - it is a licence level, not a setting. See Items, kits & dismantling.

1. Create an item for the whole, and one for each part

Every part you intend to sell needs its own item, created before you dismantle anything. The headlight, the left fender, the right fender, the radiator, the alternator.

They will normally sit in the same family as the whole, so they inherit the same accounts - see How to create an item and Item families.

2. Open a production invoice

Inventory management → Production → Production invoices → New.

Work from the bottom up, because that is the order the business happens in:

Raw materials (lower grid) - one line: the car front, quantity 1, with its warehouse and its price. This is what gets consumed.

Manufactured material (upper grid) - one line per part: headlight, left fender, right fender, radiator, alternator, each with its quantity and warehouse.

3. Split the cost with percentages

The Percentage column on each output line says how much of the raw material's cost that part carries. The percentages must total 100.

For a 1,000 USD front:

You control the split, and you should: parts are not worth equal fractions of a wreck. Weight the percentage towards what actually sells for more. If the total is not 100 the costing is wrong and the difference has nowhere to go.

4. Save, then post

Saving moves the stock: the front leaves, the parts arrive with their costs. Post To Accounting puts it in the ledger.

Dismantling only part of a whole

You rarely break everything down. The motor is often worth more intact, and a customer may want it whole.

So dismantle to the level that sells, and make an item for the remainder:

1. Put only the parts you are actually removing in the upper grid - say the bonnet and the fenders.
2. Add one more output line for what is left: an item named something like Car front - less bonnet and fenders.
3. Give the remainder the balance of the percentage, so the column still totals 100.

The remainder is now an ordinary item. Sell it whole, or run it through a second production invoice later when someone wants the motor out of it. This is how breakers normally work - dismantle coarsely on arrival, then break down further on demand.

If you do this repeatedly

A wreck is different every time, so most dismantling is done straight on the production invoice with no saved recipe.

But if you genuinely repeat the same breakdown, save it as a production formula and press Copy to turn it into an invoice each time. See Production formulas, invoices & orders.
