Accumulate sum
- 1 year ago
Hi jps_HHH ,
here's an example of how to calculate a forecast assuming a percentage growth:ForecastActualCosts = VAR _maxActualDate = CALCULATE( MAX('Cost Production Lines'[Month]), 'Cost Production Lines'[Type] = "ACT" ) VAR _futureMonths = SELECTCOLUMNS( FILTER( ALL('Cost Production Lines'[Month]), 'Cost Production Lines'[Month] > _maxActualDate ), "Month", [Month] ) VAR _forecastValue = 1.05 -- Example: 5% monthly growth RETURN SUMX( _futureMonths, CALCULATE( SUM('Cost Production Lines'[Val.in rep.cur.]) * _forecastValue, 'Cost Production Lines'[Month] <= _maxActualDate ) )Modify _forecastValue or replace the growth logic with your specific forecast method.
Now you can combine Actual and Forecast Lines:
CombinedActualAndForecast = VAR _maxdate = MAX('Cost Production Lines'[Month]) VAR _actualMaxDate = CALCULATE( MAX('Cost Production Lines'[Month]), 'Cost Production Lines'[Type] = "ACT" ) RETURN IF( _maxdate <= _actualMaxDate, CALCULATE( SUM('Cost Production Lines'[Val.in rep.cur.]), ALLSELECTED('Cost Production Lines'), 'Cost Production Lines'[Month] <= _maxdate, 'Cost Production Lines'[Type] = "ACT" ), ForecastActualCosts )
Hi jps_HHH ,
You already have this measure, but ensure it filters only for ACT:
AccumulatedActualCosts =
VAR _maxdate = MAX('Cost Production Lines'[Month])
RETURN
CALCULATE(
SUM('Cost Production Lines'[Val.in rep.cur.]),
ALLSELECTED('Cost Production Lines'),
'Cost Production Lines'[Month] <= _maxdate,
'Cost Production Lines'[Type] = "ACT"
)
Now create a similar measure but filter for BDG:
AccumulatedBudgetCosts =
VAR _maxdate = MAX('Cost Production Lines'[Month])
RETURN
CALCULATE(
SUM('Cost Production Lines'[Val.in rep.cur.]),
ALLSELECTED('Cost Production Lines'),
'Cost Production Lines'[Month] <= _maxdate,
'Cost Production Lines'[Type] = "BDG"
)
Add Month to the X-axis.
Add both AccumulatedActualCosts and AccumulatedBudgetCosts to the Values field of the line chart.
This will create two separate lines: one for the actual costs and one for the budget costs.
If your data model allows, you can use a Type column (ACT/BDG) as a legend. This will automatically split the lines by type, but only if you don't need separate measures.
It works.
But the "actual line" should stop at November and not maintain the same values for future months. And I would also like to include a forecast for "actual line" . If it will overlap the budget line in March 2025 or not.
