GetFieldProtection()

Gets a string that indicates whether a field is read-only.

field_protection_flag = GetFieldProtection(string field_spec)

Argument	Contents
field_spec	A field spec

The string "True" if the field is read-only; the string "False" if values for this field can be modified.

If a field is protected, the user cannot change its value in an editor. Other operations in Caliper Script, like SetRecordValues(), can still change its value.
Some fields are always protected. These include the linking fields in a joined view (see JoinViews() and JoinViewsMulti()), any aggregation fields (see SelfAggregate(), JoinViews(), and JoinViewsMulti()), any expression fields (see CreateExpression()), and any field on a view that is entirely read-only (see GetViewReadOnly()).
SetFieldProtection() can change the status of a field which is not always read-only (see above).

prot = GetFieldProtection("SalesRep.Salary")

Error Type	Meaning
Error	The input field specification is ambiguous
NotFound	The input field does not exist
