How is the "$key" of the rule stored in the ACF2 database?
is it different dependent on the country you are in?
The $KEY string is NOT stored in the ACF2 database.
it is only the value of the $KEY that is stored.
$KEY(SYS1) is not stored in the database with the "$KEY" only the SYS1 is stored.
The same is true for resource rules
$KEY(ABC)
$TYPE(SAF)
Will not have $KEY or $TYPE stored in the database - just the values e.g. ABC or SAF etc.
