What's new?​

The Swedish Parking of Receipts documentation now includes proforma transactions in the parking chain. New XML and JSON examples show how to send NFS="PROFORMA" with the latest ResumeFN, receive a signed fiscal number from the PF series, and use that number when continuing or finalizing the transaction. Related references and links in the business cases and ESR elements documentation have also been updated.

What this means for our users?​

POS integrators can now follow the complete Swedish flow from parking and re-parking through proforma and finalization. The examples clarify that a proforma keeps the transaction parked under its own fiscal number, and that every subsequent request must reference the fiscal number returned by the most recent step of the chain.
