Coercion Rules for Dimensional Objects

The following table describes coercion rules that are applied when coercing an object of one dimensional type into another.

Note: Measures and Member Unique Names (MUNs) are considered members.

Source type	Target type	Result
Measure dimension	Hierarchy	A measure dimension can be used without any conversion as a hierarchy.
Measure dimension	Member set	The member set contains the members of the measure dimension. This coercion is done in two steps. First, measure dimensions are coerced to hierarchies, and then hierarchies are coerced to member sets.
Hierarchy	Member set	A set containing the members of the hierarchy.
Level	Member set	A set containing the members of the level. The equivalent expression is `members` (level).
Measure	Member	A measure can be used without any conversion as a member.
Measure	Tuple	This coercion is done in two steps. First, measures are coerced to members, and then members are coerced to tuples.
Measure	Member set	This coercion is done in two steps. First, measures are coerced to members, and then members are coerced to member sets.
Member	Tuple	The tuple consists of the member. The equivalent expression is `tuple` (member).
Member	Member set	The set consists of the member. This coercion is done in two steps. First, members are coerced to tuples, and then tuples are coerced to member sets.
