updatePurchaseOrderLine

mutation · in the family Purchasing

What it does

Replace one line on a draft purchase order — its product, quantity, cost, receiving location or expected date.

REPLACE ONE line of a DRAFT PurchaseOrder WHOLE: the addressed lineNo is KEPT, every create-time gate re-runs on the replacement, and the header rollups move with it. ONE transaction — the row Put + the header rewrite. A live post-draft doc refuses CONFLICT/REF_STATE; an unknown lineNo refuses VALIDATION/INVALID naming it. Requires the doc CURRENT revision (OCC) + the unrestricted capability. NO reason — the edit class.

What happens

The whole line is rewritten and keeps its line number; anything you leave out is cleared, not kept. The order’s totals move with it.

Careful

Only while the order is still a draft — once it is issued, changing it means cancelling or closing short and raising a new order.

Who may call it

Capability area: Purchasing — Purchase orders, returns to vendors, vendor invoices and supplier records.

Arguments

inputUpdatePurchaseOrderLineInput UpdatePurchaseOrderLineInput!yesNo further notes.
revisionID ID!yesThe revision id you read on the record; the change is refused if an edit landed in the meantime.

Returns

PurchaseOrder PurchaseOrder! — A purchase order: an org orders variants x quantities x receiving LFs from ONE enabled vendor (the OrgVendor enablement — IMMUTABLE at birth). Lines live in their OWN rows since and stay draft-editable wholesale (max 1000 — the NAMED assignment ceiling, raised from 48 with the rows; at most 90 line actions per CALL, so a big order grows through addPurchaseOrderLines; the same variant to N LFs = N lines,889); currency is the OrgVendor purchasingCurrency SNAPSHOT (every Money on the family matches it — NO FX, lean 5); received/closed_short are IMMUTABLE non-doomed history; cancelled is the ONE doomed terminal (lists filter it). Re-running the same verb RESUMES a stalled walk; on a healthy in-flight order it refuses CONFLICT/IN_PROGRESS naming the progress.
