你好,我相信我们中的很多人将面临的复杂性of having nested dimensions that are not constant over time, and would therefore be different on a version to version basis. Although the idea seems to cover that, I'm not sure about the technical feasability of it, so keen to share my work around: When I have dimensions where roll-ups are not constant over time, I do not build the parent/child relationship in the list settings. Instead, I use version and child list dimensionned module with the target parent as a parent-formatted line item. Doing this means you're not able to use the native aggregations anymore between child and parent levels, but you have full flexibility over the child/parent relationship on a version basis. You then need to work with SUM aggregations in order to sum up your numbers from 1 level to the next.
