# purchaseOrderLines

query · in the family [Reading your records](/reference/reading-your-records/)

## What it does

The lines on one purchase order — what you ordered, where each lot is going, and how much of it has landed.

ONE PurchaseOrder's own lines, lineNo-ORDERED + born-paginated. purchaseOrderId is the REQUIRED anchor (tenant-scoped — a cross-tenant/missing order refuses NOT_FOUND, never an empty page). 'nextToken' = the prior page's cursor, verbatim (opaque; malformed/foreign → VALIDATION/INVALID). Requires authentication.

## What happens

Reads only — changes nothing. Comes a page at a time, in line order, and can be narrowed to one product, one receiving location, or an arrival window.

## Who may call it

## Arguments

| Name | Type | Required | Notes |
| --- | --- | --- | --- |
| `purchaseOrderId` | [ID](/types/#scalars) `ID!` | yes | No further notes. |
| `filter` | [FilterInput](/types/FilterInput/) | no | Which records to answer — clauses over the family’s filterable fields (the FilterInput type and the paging guide carry the grammar). |
| `sort` | [SortInput](/types/SortInput/) | no | The order to answer in — one declared field and a direction (the SortInput type carries the grammar). |
| `limit` | [Int](/types/#scalars) | no | How many records to answer at most; a page may hold fewer. |
| `nextToken` | [String](/types/#scalars) | no | The cursor from the previous page, passed back exactly as received. |

## Returns

[PurchaseOrderLinePage](/types/PurchaseOrderLinePage/) `PurchaseOrderLinePage!` — One page of a PurchaseOrder's own line collection.

This is a page: `items` holds the records and `nextToken` the cursor for the next page — pass it back verbatim until it is null. See [paging](/guides/paging-and-the-cursor-grammar/).
