Thanks for the suggestion Gary. But in that case, with a service in archive_
services (after StdArchive) or in report_services , it is a read-only access to
the full archive record.
The idea of my service was to read some GW1000 sensor archive record values,
and depending on these value modify another non-GW1000 archive record value.
If I understand well, this has to be done before StdArchive, i.e before the
archive record is finalized and written to the database.
