hello all,

i saw a dictionary defined in field operator (see below) with name “template”. does it apply only to this operator or apply to the whole template?

string name=“SecurityID” id=“48”

delta dictionary=“template”/

/string

fast specification indicates there are 3 predefiend dictionary, “template”, “type” and “global”, are they “name” sensitive?

please advise

thanks & regards
