Returns the specified member and all the ancestors of that member, including ancestors of any occurrences of the specified member as a shared member. You can use this member set function as a parameter of another function, where that parameter is a list of members.
@IALLANCESTORS (mbrName)
mbrName | A valid single member name or member combination, or a function that returns a single member or member combination. |
Analytic Services sorts the generated list of members in ascending order of the member number in the outline. Using Sample Basic as an example, if you specify 100-20 for mbrName, Analytic Services returns 100-20, 100, Diet, Product (in that order). However, the order in which shared ancestors are returned is not guaranteed. This order is important to consider when you use the @IALLANCESTORS member set function with certain forecasting and statistical functions.
The following example is based on the Sample Basic database. Sample Basic has a shared level of diet drinks, which includes 100-20 (Diet Cola). So 100-20 (Diet Cola) is a descendant of 100 (Colas) and is a shared member descendant of Diet:
100 100-10 100-20 ... Diet 100-20 (Shared Member) ...
The following calculation script increases by 5% the Budget Sales values of 100-20 and all its ancestors, including Diet:
FIX(Budget,@IALLANCESTORS("100-20")) Sales = Sales * 1.05; ENDFIXThis example produces the following report. This report shows that the Budget->Sales values for 100-20, 100, Diet, and Product (100-20 and its ancestors) have been increased by 5%. The original values were 2610, 8980, 8260, and 28480, respectively.
