Receipt Case Definitions

This chapter expands on the definitions of Receipt Cases covered in Chapter "Receipt Case Definitions" of the General Part, with country-specific information applicable to the Polish market.

Processing overview

How the Middleware processes each receipt case category in Poland:

Category	Cases	Polish processing
Receipt	0000, 0001, 0004	Sent to the certified register through the SCU; the register assigns the fiscal document number and reports to the CRK. 0000 (unknown) is handled like a POS receipt (0001).
Receipt	0002, 0003	Recorded by the queue only (no register interaction). 0003 covers sales outside the fiscalization obligation.
Receipt	0005–0007	Rejected as not supported for the Polish market.
Invoice	1000–1003	Never sent to the register. Persisted by the queue and marked with the signature "Stored, not fiscalized" (0x504C_2000_0000_0106); fiscalization happens via KSeF once a KSeF SCU is configured.
DailyOperations	2000	Zero receipt — reads the register status through the SCU.
DailyOperations	2011	Daily closing — triggers the legally required daily (Z) report (raport dobowy) on the register.
DailyOperations	2012, 2013	Monthly/yearly closing — trigger the periodic report on the register.
DailyOperations	2001, 2010	Recorded by the queue only.
Log/Protocol	3xxx	Recorded by the queue; no register interaction.
Lifecycle	4001	Initial operation — registers the queue and verifies via the SCU that the connected register reports itself as fiscalized (fiscalizing the register itself is a certified-technician act).
Lifecycle	4002	Out of operation — deregisters the queue.
Lifecycle	4011, 4012	Acknowledged without register interaction.

Constraints enforced by the queue

• Currency PLN on the receipt and on every charge/pay item (error code CurrencyMustMatchMarket).
• No mixed sale and return positions in one document — returns are separate documents on the register side.
• Paragon z NIP: the ReceiverIsBusiness flag requires the buyer's NIP as CustomerVATId in cbCustomer.
• Register unreachable: fiscal cases fail with 0x504C_2001_EEEE_EEEE (Art. 111(3) — no working register, no sale).
