getPurchaseDocuments

Returns a list of purchase documents (purchase invoices or orders), according to the supplied filtering parameters.

If you have specified document ID or invoice number, or if the search criteria match a single sales document, or if you have set getRowsForAllInvoices = 1, API returns all documents together with their rows. Otherwise only document headers will be returned.

If you are looking for a way to pull all purchase data for external processing, see getPurchaseReport. getPurchaseReport can output either detailed data or aggregate it as needed: it can provide totals by products, by product groups, by dates, by locations, etc.

Response

Field name Type Description

id integer Purchase document ID

type

string

If your account has configuration setting use_purchase_waybills enabled, then the possible types are:

PRCORDER	Purchase order
PRCINVOICE	Purchase invoice-waybill. Takes items into stock and affects your Accounts Payable. A Purchase Invoice-Waybill is equivalent to making a Purchase Waybill (PRCWAYBILL), followed by a Purchase Invoice (PRCINVOICEONLY)
CASHPRCINVOICE	Purchase receipt. Same as previous.
PRCRETURN	Purchase return. Functionally same as a purchase invoice-waybill, but it is used to return goods back to supplier. On a purchase return, amounts are negative.
PRCWAYBILL	Purchase waybill. This document ONLY takes items into stock, and does not generate an obligation to pay.
PRCINVOICEONLY	Purchase invoice. This is usually a follow-up for the items that have arrived earlier with an invoice-waybill. For example, the supplier may send shipments continuously throughout the month, and bill the customer once a month, for all the shipments sent. The invoice does not affect stock, but it affects your Accounts Payable.

If the setting is not enabled, possible types are:

PRCORDER	Purchase order
PRCINVOICE	Purchase invoice-waybill. Takes items into stock and affects your Accounts Payable. (Here, we can also call it a "purchase invoice" for short, since there are no other similar document types.)
CASHPRCINVOICE	Purchase receipt. Same as previous.
PRCRETURN	Purchase return. Functionally same as a purchase invoice-waybill, but it is used to return goods back to supplier.
COMMITMENT	Purchase commitment.
COMMITMENT_DEDUCTION	Commitment Deduction.
AVAILABILITY_CHANGE	Availability Change.

status

string

The possible statuses are:

PENDING	Document not confirmed.
PARTIALLY_RECEIVED	Purchase order (PRCORDER) only. Document has been confirmed and its status is "partially received". This status can be set manually, but typically this means that the PO has been associated with a purchase invoice, or purchase invoices, but not all ordered items have been received yet.
RECEIVED	Purchase order (PRCORDER) only. Document is confirmed and its status is "received".
READY	Any other confirmed purchase document (for example a purchase invoice or a purchase return) — or a confirmed purchase order that has not been fulfilled yet.

currencyCode string Currency code: EUR, USD.

currencyRate number eg. 1.25543
Exchange rate of the purchase document currency against system's default currency.

warehouseID integer ID of the warehouse

number string Number of purchase document

regnumber string Reg. number of purchase document

date string Format: yyyy-mm-dd. eg. 2010-01-29

This is the date on which the document was confirmed and when the items on this document were added into inventory, or removed from inventory. While "document date" can be edited by users at any time, "inventory transaction date" is always set by Erply and cannot be changed.
Inventory Reports and COGS reports are based on the inventory transaction date.
