Percent of Weight Parent
This aggregate works like Percent of Parent, with the difference that a value from one column is compared to a parent level sum of values from another column, which is set as the “Weight column”:
[single child node value from a column] / [sum of all child node values from weight column in the group]
While Percent of Parent will always summarize to 100% at the group (parent) level, this is not the case with Percent of Weight Parent, which can summarize to any number, depending on the differences between the Values and the Weight Values.
The aggregate value is calculated as a ratio between 0 and 1 and will be presented as a percentage value by applying a percent format string in the aggregation settings.
