Hi Rt0790,

Hi, thanks for the information you have given.

Please use the following DAX to create Calculated columns:

Score Week Beginning =
VAR CurrentWeek = 'Table'[Week]
VAR CurrentScore = 'Table'[Score]
RETURN
    IF(
        CurrentWeek = MIN('Table'[Week]),
        0,
        CALCULATE(
            SUM('Table'[Score]),
            FILTER(
                ALL('Table'),
                'Table'[Week] < CurrentWeek
            )
        )
    )

Score Week Ending =
VAR CurrentWeek = 'Table'[Week]
VAR CurrentScore = 'Table'[Score]
RETURN
    IF(
        CurrentWeek = MIN('Table'[Week]),
        CurrentScore,
        CALCULATE(
            SUM('Table'[Score]),
            FILTER(
                ALL('Table'),
                'Table'[Week] <= CurrentWeek
            )
        )
    )

To achieve the expected result of calculating the running totals of the score column from the week starting to the week ending for each student, you can use DAX formulas in Power BI. Here's how you can create a new table or a calculated column to get the desired result:

1. Create a New Table or Use a Calculated Column: You can create a new calculated table or use a calculated column to generate the running totals for each student based on the week starting and week ending.

Here's a DAX formula for the calculated table approach:

ExpectedResultTable =
VAR CurrentStudent = 'YourTableName'[Student Name]
VAR CurrentWeek = 'YourTableName'[Week]
RETURN
ADDCOLUMNS(
FILTER(
'YourTableName',
[Student Name] = CurrentStudent && [Week] <= CurrentWeek
),
"Score Week Beginning",
CALCULATE(
SUM('YourTableName'[Score]),
FILTER(
'YourTableName',
[Student Name] = CurrentStudent && [Week] <= CurrentWeek
)
),
"Score Week Ending",
CALCULATE(
SUM('YourTableName'[Score]),
FILTER(
'YourTableName',
[Student Name] = CurrentStudent && [Week] <= CurrentWeek
)
)
)

1. Replace 'YourTableName': Make sure to replace 'YourTableName' with the actual name of your table where you have the student data.

2. Apply the DAX Formula:

• Go to Power BI Desktop.
• Create a new table using the DAX formula provided above.
• You will get a new table with columns "Score Week Beginning" and "Score Week Ending" that will give you the running totals based on the week starting and week ending for each student.

This DAX formula will calculate the running totals of the score column for each student from the starting week up to the current week, giving you the expected result table as shown in your example.
