Returns all descendants of the members in the specified member list
or all descendents down to the specified generation or level. This function
excludes the specified members.

You can use the @LDESCENDANTS function as a parameter of another function,
where the function requires a list of members.


@LDESCENDANTS ((memberSetFunction) [,genLevNum])
Parameter Description
memberSetFunction A member set function that returns a list of members.

How the @LDESCENDANTS function is used determines which member set functions
are allowed. Follow these guidelines:

  • If the @LDESCENDANTS function is used alone (not within a
    FIX statement), you must use the @LIST function and specify member names.
    For example:

  • If the @LDESCENDANTS function is used within a FIX statement,
    you can use member set functions such as @UDA and @ATTRIBUTE. For example:

    @ATTRIBUTE (attMbrName)

    In this case, you can choose whether to use the @LIST function. For
    example, both of the following statements are valid, and the statements return
    the same results.

    Example using only @ATTRIBUTE:


    Example using @LIST and @ATTRIBUTE:



All members of the specified member list must be from the same dimension.

genLevNum Optional. The integer value that defines the absolute generation or
level number up to which to select members. A positive integer defines a generation
number. A value of 0 or a negative integer defines a level number.

Florida, Connecticut, and New Hampshire (the descendants of the specified
member East); and Illinois, Ohio, Wisconsin, Missouri, Iowa, and Colorado
