Inventory snapshot

Hi,

I have to store inventory snapshot for total stock quantity in a new cube. Daily movements are captured through delta everyday in a different cube.

Now i am planning to create a query on regular cube and through APD fetch snapshot to the new cube. I only need total stock.

I am unclear about below points

1. I need snapshot at Material,plant,batch,sloc and stock type and there are no time characteristics too be used, i mean full snapshot.Will it work with aforementioned approach?

2.The new cube ha no BWA indexes on it since its not available in system. If i fetch full snapshot from query built on this cube using APD will it be performance efficient , i mean APD run time.

Regards
