I have an ART with multiple teams using the same PI planning level. The planning level can only have one sprint schedule which is fine except for the Target Estimate for each sprint. This is the field used by the Velocity Trend report to show the diamond of what teams planned at the start of the sprint vs what they actually achieved. Since it is at the Sprint Schedule and not at the team level, this field can only reflect the total for the ART for this PI for a sprint rather than one per team and then roll I t up to the ART level.
