this is my dataset:
I want to calculate the "Cover Month". Therefore I have to look for Stock(in this example in january 2016 = 5,000), then have a look for each future month if current stock(january 2016) is bigger than "cum. Sales" of following month. If yes, then remember value = 1. This should be done for each future month. After this step all remembered values should be added, so result is 4 (Cover Month). Stock will be enough for 4 following months.
Next step system should do this for next month - dynamically for each month...
How can I do this in a performant way?
Is this the right way:
Filter([TIME].[Year to Month].currentmember : NULL,
[Measures].[cum Sales] < [Measures].[Stock])
?
Maybe anybody can give me a hint? Or maybe I need another alternative formula to get a subtotal and then do another calculation?
Thanks in advance, Andy
