Subcontracted production: sent materials, progress and returns

Material left your warehouse; you still need to know what was transformed, what returned and what remains in external custody.

Subcontracted material reconciliation

Ten tests of dispatch, transformation, partial receipt, unused returns and external-custody discrepancies.

What should identify external work?

Record workshop or supplier, order, effective recipe, materials, lots and units. A component may be outside your site in the workshop's custody without implying sale, complete consumption or loss. Define who reports progress, who receives and who accepts. Contractual relationships and accounting treatment require their own review; this control explains operational quantities and does not determine legal ownership.

Odoo describes resupplying components to a subcontractor that manufactures the product and delivers finished goods. Its workflow distinguishes component dispatch and output receipt. Resupply subcontracting. Verify routes and documents for your configuration: multistep warehouses may need additional validations. That documentation does not establish your loss tolerances or acceptance criteria.

Example: one hundred components, two partial deliveries

StageAccepted setsUnused returnedAccepted lossComponents still outside
Dispatch S01000100
Receipt P0125 = 50 components5243
Additional receipt P0215 = 30 components1030
Total40 = 80 components1550

Forty-three remain after P01: one hundred minus fifty incorporated, five returned and two accepted lost. P02 explains those forty-three as thirty incorporated, ten unused and three lost. The final total is eighty plus fifteen plus five, equaling one hundred. Do not add forty sets and fifteen components as if they shared a unit; retain the exercise recipe's two-components-per-set relationship.

What does the workshop's report prove?

A photo or '25 ready' notice reports progress. It does not establish arrival or inspection acceptance. Retain reported, in-transit, received and accepted quantities when your process distinguishes them. If twenty-five arrive and quality holds two, acceptance shows twenty-three and two pending, while components incorporated in all twenty-five remain explained. A rejection does not automatically make those components lost without determining the sets' disposition.

ERP36 publishes sent-material and received-product controls for subcontracted production. Subcontracting features. This is a vendor description, not independent verification of its results. Use it to compare coverage and require your own partial case. If the workshop declares five lost without support, retain the statement and review item; do not mark outside stock zero as though its explanation were accepted.

When can you close the job?

Close when every sent component has an explainable destination and outstanding decisions remain identified. An external balance may be work in progress, unused stock awaiting return or a discrepancy under investigation. Distinguish a usable return from damaged material arriving back. Keep dispatch, receipt and disposition documents; correcting an entry must reference the prior data rather than erase the workshop's history.

What should the demonstration establish?

  • Normal: S01, P01 and P02 reconcile by job, component and recipe; both receipts result in 40 sets.
  • Exception: declared loss without a decision retains its pending item and owner; it cannot silently close the balance.
  • Quality: received, held goods retain location and their relationship to incorporated material.
  • Retry: repeating P01 neither adds another 25 sets nor returns another five components.
  • Change: different quantities under the same report identity require review; a new delivery uses its own reference.

What should you bring to a diagnosis?

Complete the external materials worksheet with one job and an incomplete return. Materials revisions explain equivalents; inventory between warehouses covers internal transfers. To scope production control, also bring a workshop report that disagrees with receipt. The difference defines concrete states and decisions without promising that any supplier portal proves completed work.

Review a partial delivery from an outside workshop

In a free diagnosis we can separate dispatched, reported, received and still unexplained quantities.

  • One component dispatch with lots and quantities.
  • The recipe and a partial workshop report.
  • Receipts, unused returns or losses that do not reconcile.

Frequently asked questions

Do not assume so. Distinguish external location, reported consumption and received output under your configuration's rules and documents.

No. It can support reported progress. Arrival, received quantity and inspection require their own records.

Only through a relationship defined in a relevant recipe. The example uses two components per set; do not generalize that equivalence to other products.

Retain its statement and a pending item with an owner. Operational closure should not present disputed loss as accepted disposition.
