ACK / MSG — society response

When a society processes your file it answers with an ACK transaction per original transaction: the status (accepted, rejected, conflict…), MSG lines detailing any problems, and a copy of the original transaction as received. Note that embedded originals keep the original file's sequence numbers.

The exact field layout — positions, sizes, and formats — is defined in CISAC's CWR specification (CWR19-1070R1), available to CISAC members and licensees. The validator implements the full layout: drop a file on it and every ACK / MSG line is parsed field by field, with problems tied to the exact characters at fault.

More: all record types · what a CWR file is · every error explained.

Two free checks for your CWR file. Is the file correct? Every record, share and control total against the spec, each problem on its exact line. Do its writers match their registrations? Every writer cross-checked against public registration data, including works registered under another spelling or IPI. Nothing stored: check a file at cwrcheck.com.
