BEX provides another way for simplifying expressions using the concept of unique scope. For example, if there is only one policy in the scope of expression, the user can write 'effective date' instead of 'effective date of the policy'. BEX automatically determines the uniqueness of the attribute and either produces a correct path or emits an error message in case of ambiguous statement. The level of the resolution can be modified programmatically and by default equals 1.
