Need help in Building Burn Up (Commitment Vs Delivered)

Hi JeevanMallya ,

Thank you for reaching out to Microsoft Fabric Community.

Here are some steps to follow to achieve the requirement:

1.Create a Separate Sprint Table

This avoids circular dependency and helps us sort properly.

Go to Modeling → New Table (SprintTable)--You can find logic in attached .pbix file.

2.Sort Sprint Name
After table is created:

Go to SprintTable - Click on SPRINT_NAME

Choose Sort by Column - Select SprintOrder

3.you must create a relationship between SprintTable and your main data table (Sheet1) to allow proper filtering and avoid DAX errors.(Check in .pbix file)

4.Created 4 measures as shown in pbix file.(1.Committed 2.Completed 3.Cumulative_Committed 4.Cumulative_Completed.)

5.Build the Burn up Chart

Use a Line Chart:
X-axis: SprintTable[SPRINT_NAME]

Y-axis:Cumulative_Committed,Cumulative_Completed.
