persist future values from measure - powerbi

Question

I have a measure which displays number of employees in relation to the date.
Each day the FactEmployee is updated to reflect who is working. this means that my measure (obviously) can't display how many employees there are tomorrow.
I would like to persist the latest value (ie. todays value) into the future.
Data model
My (not perfect) measure
Count, employee :=
VAR today = TODAY()
VAR res =
IF (
MAX ( DimDate[fulldate] ) > today,
CALCULATE (
COUNT ( DimEmployee[emp_key] ),
FILTER ( ALL ( FactEmployee ), RELATED ( DimDate[fulldate] ) = today)
),
CALCULATE ( COUNT ( DimEmployee[emp_key] ), FactEmployee )
)
RETURN
res
Output
year-month count, emp
---------------------------
2020-01 182
2020-02 180
2020-03 174
2020-04 171
2020-05 171
2020-06 173
2020-07 172
2020-08 175
2020-09 172
Expected Output
year-month count, emp
--------------------------
2020-01 182
2020-02 180
2020-03 174
2020-04 171
2020-05 171
2020-06 173
2020-07 172
2020-08 175
2020-09 172
2020-10 172 <----repeated value from 2020-09
2020-11 172 <----repeated value from 2020-09
2020-12 172 <----repeated value from 2020-09
how can i fix my measure to get the missing values (oktober to december)?

Answer 1

I have replicated your model using a simplified version, I don't think you need dimEmployee in this case.
Assuming your model is like this
And your tables look like these:
FactEmployee
+----------+---------+
| date_key | emp_key |
+----------+---------+
| 20200101 | 1 |
+----------+---------+
| 20200102 | 1 |
+----------+---------+
| 20200103 | 1 |
+----------+---------+
| 20200104 | 1 |
+----------+---------+
| 20200105 | 1 |
+----------+---------+
| 20200101 | 2 |
+----------+---------+
| 20200102 | 2 |
+----------+---------+
| 20200104 | 2 |
+----------+---------+
| 20200101 | 3 |
+----------+---------+
| 20200102 | 3 |
+----------+---------+
| 20200103 | 3 |
+----------+---------+
| 20200104 | 3 |
+----------+---------+
| 20200105 | 4 |
+----------+---------+
DimDate
+------------+----------+
| Date | Date_key |
+------------+----------+
| 01/01/2020 | 20200101 |
+------------+----------+
| 02/01/2020 | 20200102 |
+------------+----------+
| 03/01/2020 | 20200103 |
+------------+----------+
| 04/01/2020 | 20200104 |
+------------+----------+
| 05/01/2020 | 20200105 |
+------------+----------+
| 06/01/2020 | 20200106 |
+------------+----------+
| 07/01/2020 | 20200107 |
+------------+----------+
I have created a calculation that follow these steps:
Compute the maximum date with valid or non blank values for the distinct count of emp key, under the variable MaxDateKey.
IF statement evaluated for date_key greater than 'MaxDatekey' - in this case 20200106 and 20200107. For those dates, the calculation retrieves the distinct count of emp_key for MaxDateKey.
When the IF stamenet is false, distinct count is calculated as usual.
Count =
VAR MaxDateKey =
CALCULATE (
LASTNONBLANK ( FactEmployee[date_key], DISTINCTCOUNT ( FactEmployee[emp_key] ) ),
REMOVEFILTERS ( DimDate[Date] )
)
VAR Result =
IF (
MAX ( DimDate[Date_key] ) > MaxDateKey,
CALCULATE (
DISTINCTCOUNT ( FactEmployee[emp_key] ),
ALL ( DimDate[Date] ),
DimDate[Date_key] = MaxDateKey
),
DISTINCTCOUNT ( FactEmployee[emp_key] )
)
RETURN
Result
The output below. The values from the last valid date 5th of Jan is applied to the subsequent dates (6th and 7th of Jan).

For line chart, you can check the Forecast option from the Analytics pane as shown below.
The output will be something like below-
