Hello Everyone,
Im trying to calculate a product price index. In my case a Avg. Rolling 12 month measure versus the Avg. Rolling 12 Month price from 2 years ago (this is the tricky part for me, as my denominador has to be always the January of 2 years ago.)
Formula : (100) * ( Avg.R12M Dec 2018 price / AvR12M January "2016"*)
Where January 2016* is the comparison point of my index, and it will always be the start point equal to 100.
I having big problems with setting a dynamic denominator for this formula. it has to consider the actual Avg.12RM let say Dec 2018, and compare it versus the Avg.12RM price of January 2016.
So basically i need to accomplish 3 steps:
1) Calculate a rolling 12 month of daily prices by product.
2) Create a dynamic measure as initial point of my index: set as January of 2 years ago.
3) Set the a dynamic Line graph that changes acording the denominador to display the correct versus "January" result.
The final formula would be = (100) * ( Avg.R12M Dec 2018 price / AvR12M January 2016*), but at the same time being dynamic enough, as next month 2019" it would move the denominator 1 year to become Avg.R12M January 2017.
Any help or suggestions?
Thanks,
Hi,
Share some data and show the expected result.
I'm not sure how to share data.
A mega link to PBI dummy date is : https://mega.nz/#!GGR12IAY!j4rB4ePWNDXI4QqOynlwVJbPEiPayGEVT53ZKjYP_gM
and the basic idea is I got the item prices in a daily basis, then I need to convert that into monthly avg, and 12RM monthly avg to finally compare it agains a baseline date. That basically is January of 2 years in the past.
Hi,
Sorry but i cannot understand your requirement. Could you show your expected result on an Excel file with formulas so that i can translate those Excel formulas into the DAX formula language.
