Returns the specified member and either all descendants of the member or all descendants down to the specified generation or level.
Essbase sorts the generated list of members—starting with the specified member, followed by the nearest descendant of the member, followed by the next nearest descendant of the member, and so on. In the Sample.Basic database, if you specify @IDESCENDANTS(100), Essbase returns 100, 100-10, 100-20, 100-30 (in that order). When using the @IDESCENDANTS function with certain forecasting and statistical functions, you must consider order.
You can use the @IDESCENDANTS function as a parameter of another function, where the function requires a list of members.
@IDESCENDANTS (mbrName[, genLevNum | genLevName])
Valid member name or member-name combination or a function that returns one member or member combination.
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.
Optional. The level or generation name up to which to select members.
All examples are from the Sample.Basic database.
