@RDESCENDANTS

Returns all descendants of the specified member, or those down to the specified generation or level, including shared members. This function excludes the specified member.

You can use this member set function as a parameter of another function, where that parameter is a list of members.

In the absence of shared members, @RDESCENDANTS and @DESCENDANTS return the same result.

Syntax

@RDESCENDANTS (mbrName [, genLevNum| genLevName])

Parameter	Description
mbrName	Any valid single member name or member combination, or a function that returns a single member or member combination
genLevNum	Optional. An integer value that defines the absolute generation or level number down to which to select the members. A positive integer defines a generation number. A value of 0 or a negative integer defines a level number.
genLevName	Optional. Level name or generation name down to which to select the members.

Notes

The order of members in the result list is important to consider when you use the @RDESCENDANTS member set function with certain forecasting and statistical functions. Essbase generates the list of members in the following sequence: If a shared member is encountered, the above steps are repeated on the member being shared.
1. The specified member
2. The nearest descendant of the member
3. The next nearest descendant of the member, and so on.
You can use @IRDESCENDANTS to include the specified member in the member list.

Example

Example 1

Assume a variation of the Sample Basic database such that the Product dimension includes the following members:

Product
   100
     100-10
     100-20
     100-30
   200
     200-10
     200-20
     200-30
     200-40
   Diet
     100 (Shared Member)
     200 (Shared Member)

Diet has two children "100" and "200". The members "100" and "200" are shared members.

@RDESCENDANTS(Diet)

returns the members: 100, 100-10, 100-20, 100-30, 200, 200-10, 200-20, 200-30, 200-40 (in that order).

Example 2

@RDESCENDANTS(Profit)

returns Margin, Sales, COGS, Total Expenses, Marketing, Payroll, and Misc (in that order) and is identical to @DESCENDANTS(Profit).
