I need to do simple forecast based on current sale and time left to end of month.
I have 4 short tables:
Office name | Office ID
Date | Day of week
Date | Office ID | Sale value
Hours when offices are open
Office ID|Day of week|Noumber of Hours
Actualy I just show sales over date perr office but I need to add forecast.
We have 2019-03-24 - sales of current month is '150 000', offices were open 150hours in total. To end of month it is left 50hours. Soo sales per hour is (150 000/150) = 1000. So forecast will be 100*50=50 000 (+150 000).
How too do this in power bi (dax) and how to spread this value (50k) for days between 25-31.
I want to show on char value of sale day by day from 1-24 march and forecast from 25-31.
Please help. (sorry for my bad english )
