GRH / GRT — group header and trailer

Transactions travel in groups of one type (all NWR, all REV, all ACK…). GRH opens a group and declares its type and CWR version; GRT closes it and states the control totals a society checks before trusting the contents.

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 GRH / GRT 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.
