No download is available for this dataset yet. It is catalogued here so the record layout and code lookups are at least written down.
What this is
P4A002. The P-4 is the certificate that authorises product to leave a lease and names who may take it. Without an approved P-4 a lease cannot legally sell.
It is the commercial layer over the production data: the same lease keys, plus the purchaser and transporter relationships.
What you can do with it
See who buys and transports from a lease, trace a purchaser's footprint across the state, and find leases whose authorisation has changed.
Gotchas
EBCDIC.
A P-4 names authorisation, not actual transactions — an authorised purchaser may take nothing.
EZRRC does not parse this file. Upstream has not built a reader for it yet, so the catalog documents it and links to the Commission's own copy rather than pretending to serve rows it does not have.
