Examples
The IsLeaf function is used to determine whether a member in a hierarchy is a "leaf" node, meaning it has no children. In a hierarchical structure, leaf nodes are the lowest-level members that do not have any descendants.
IsLeaf([Products].^[Products].CurrentMember)
Parameters
- member: The member in the hierarchy that you want to check.
Returns
The function returns a boolean value:
- TRUE if the member is a leaf node (i.e., it has no children).
- FALSE if the member has children (i.e., it is not a leaf node).
