Power BI Paginated Report - Resetting the RunningValues for a group.

Hi,

  I have a parent Group and Child Group. Finding the cumulative total of 2 columns and finding diff of these 2 columns for the parent Group.

Once the Group value changes, the cumulative value (Using RunningValue is used to get the cumulative ) is not getting reset to 0, It is still retatining previous group value.

Would like to get the cumulative total for each group.

Used the groupname inthe RunningValue function but not working.

Any Suggetions...
