Hello,
at first, I have to say i'm german developer, so my english isn't the best.
Now to my relevant question which I describe with following small situation.
I have a very simple product dimension with product_id and product_start_wid, that mark the first day of sale.
DimProduct
-----------
product_id
datekey
Of course there is an small DimDate with the known fields.
The fact table FactTurnover have the structure:
FactTurnover
-------------
store_no
datekey
gross_profit
In words, the FactTurnover has Information about gross profit per day and store.
My target is, that the Cube provide the gross_profit per store in time granularity 1,3,7,14 day(s) after first sale per product.
Example:
store_no|product_id|gross_profit_after_1_day|gross_profit_after_3_days| ...
100 |1 |10 |40
100 |2 |20 |67
300 |2 |50 |120
Every product have an other first day of sale.
I have no beginning for this task. My knowledge in SSAS (cube building) is okay, but i haven't experience with MDX. I think a solution per MDX could be the best.
Thank for your help.
