Dataflow Aggregation not Working

I have two entity trees:

A -> B -> C
and,
P -> Q -> R

I have a cube dimensioned: (Month, C, Q), and I want to populate another cube aggregated by R: (Month, C, R)

When I build the layout (Month, C, R) in a dataview it shows the data the way i need it do, but when I run a dataflow to populate a cube with the same layout, it doesn't write any data.

This appears to be because the data is sitting in cells which intersect with C, but there's no data in the base entity A.

Is there any way around this?

    Hi Mark,

    No, there's no workaround for the issue mentioned. You'll have to map at least one member from C to one member of A for your dataflow to work correctly.

    Are you doing:

    Block     Dimensions
    A            Month, C, Q
    B            Month, C, R

    Formula: B = A

    Where B is currently Empty, and A has the data at the level under R (and Q -> R relationship is fully populated)?

    Also, what version of Board are you on?  For 12 you may need to walk it thru a TEMP cube in your procedures (I have had sporadic issues where going straight from 1 cube to another sometimes works, sometimes doesn't).  It will also potentially depend on your settings under Calculation Domain.

    Hi Mark,
    Have you looked at the sparsity settings of your cubes? Are CQ and CR all sparse in both cubes? Have you tried enabling the "extend" option under calculation domain? That should allow you to overcome it. Please share how it goes
