Summary:

Source Hierarchy not considering when destination is Allocation to Parent/Sibling

Content (please ensure you mask any confidential information):

0001 : Payables 0001: All Payables Number of Records Active Vendors 0002 : Reivables 0002: All Reivables Number of Reivables Active Customer 0003: Purchases 0003: All Purchases Number of POs Active suppliers

we have Dimension hierarchy as above and in allocation rule source Member = 0001, destination selected = "Allocate to Sibling" for the given dimension and all other dimensions are "Same As Source". this is allocating data for both 0002 & 0003 child members as per the driver ratio but not allocating anything to 0001 child members.

If we select destination 'allocate to Parent' Then it will be allocating to all three-parent member's Children's as per the driver ratio, though, source = 0001
