Resolve the discrepancy before treating the order as a clear production release. Tell the supplier exactly which references conflict and ask what is currently governing manufacture. Do not assume document priority alone prevents the wrong revision being used on the shop floor. Contractual priority questions belong with the responsible buyer.
Place the conflict in a clear document comparison
Put the purchase-order line, acknowledged drawing reference and attached file versions in one comparison. Include the part number and affected quantity. Confirm whether the supplier cited an old revision by mistake or actually priced and planned that version.
Retrieve the revision change record so both sides can see the relevant differences. The quality-agreement guide explains broader quality responsibilities; the immediate task is to establish a shared manufacturing and inspection reference. Avoid a vague request to “use the latest drawing,” since different systems may hold different files.
Confirm the intended revision and commercial effects with both parties
Ask the drawing owner to confirm the intended revision and explain any changes affecting price, tooling, delivery or verification. The buyer can then discuss commercial consequences with the supplier without implying that a technical correction automatically leaves every other term unchanged.
Determine whether material has been ordered or production started. Identify any work performed against the disputed revision and keep it separate for review. Do not let a corrected acknowledgement retroactively make earlier production conforming without checking the affected requirements.
If the parties disagree about what was ordered, escalate that issue through the applicable contract process. This workflow is a practical recommendation for document reconciliation, not legal advice that one document always overrides another. Continue clarifications while keeping the technical release status explicit.
Issue corrected controlled documents before treating the order as released
Issue a corrected, controlled document set that names the agreed drawing revision and any approved commercial changes. Ask the supplier to acknowledge the specific file and scope. Replace obsolete attachments in the active release pack while preserving them in the order history.
For the snow-plow blade order, make the inspection and packing records point to the same revision. If an agreed deviation allows a limited quantity to an earlier version, identify it separately rather than blending two revisions under an unqualified order confirmation.
Close the discrepancy when manufacturing, purchasing and receiving can all identify the governing file without interpreting the email sequence. Record who authorized the resolution and what happened to any work already completed. A clean acknowledgement is useful only when the production and acceptance records follow the resolved requirement as well.
