DATESBETWEEN / DATESINPERIOD - How to make dynamic for a predictive calcuation
My task is to create a visual to show a predicted Stock level for a warehouse for the next N days. The N is decided by planned delivery dates, it could be three days in the future or thirty. Let me over-simplify the data to explain my problem:
I have two tables for current stock level: Warehouse.Level;
And planned deliveries: Delivery.DeliveryID, Delivery.Quantity, Delivery.DeliveryDate.
I want to write a measure that predicts the changing stock level over the coming days. For each row I need to start with my current Warehouse Level and then add all the delivery quantities from the earliest date to each day in the table. The reference point is always the current Warehouse.Level which we can say is 100, Example:
| Date | Warehouse Level | Planned Deliveries | Predicted Warehouse Level |
| 01.02.2022 | 100 | 50 | 150 |
| 02.02.2022 | 25 | 175 | |
| 03.02.2022 | 75 | 250 |
The output I need is:
| Date | Prediction |
| 01.02.2022 | 150 |
| 02.02.2022 | 175 |
| 03.02.2022 | 250 |
To get the prediction over the coming days, I decided to use the DATESBETWEEN function but this is where I fail!
MyMeasure = CALCULATE( SUM(Warehouse[Level]) + SUM(Delivery[Quantity]),
DATESBETWEEN(Delivery[DeliveryDate], TODAY(), The_date_of_the_row ) )
Now the problem is that third expression in DATESBETWEEN because it needs to be the row date, which is dynamic and I cannot figure out how to get it in the statement! Same issue with DATESINPERIOD. Any idea?
Anonymous , datesbetween and dateinperiod will require date table
MyMeasure = SUM(Warehouse[Level]) + CALCULATE( SUM(Delivery[Quantity]),filter(allselected(Delivery), Delivery[Date]<= Max(Delivery[Date])))
Any time you want to date of the row use min or max
example
LTD =
var _max = if(isfiltered('Date'),MAX( 'Date'[Date]) , today())
var _min = Minx(ALLSELECTED('Date'),'Date'[Date])
return
CALCULATE([net] ,DATESBETWEEN('Date'[Date],_min,_max))Rolling 12 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date ],MAX(Sales[Sales Date]),-12,MONTH))
