Why Am I Getting a Cascading Metric Error Message?

A parent metric cannot contain existing data.

A parent metric cannot contain data because it automatically sums the values of its child metrics. If you attempt to assign a parent metric that already has data, you will see this error:

"Parent metric history is preventing the addition of a child metric."

To resolve this issue:

1. Create a new metric to act as the parent.
2. Ensure the new parent metric has no data entered in its actual column.
3. Assign the child metrics to the new parent metric.

Once set up, the parent metric will automatically calculate totals based on its child metrics.
