I have a multi-partitioned asset with two dimensions

projects

(dynamic partition) and

weeks

(time partition). I want to create a downstream asset that is partitioned only on the

weeks

dimension, so that it can aggregate across

projects

. Is this possible? I see

MultiToSingleDimensionPartitionMapping

, which seems relevant and I realize is experimental, but I’m looking at the source and I can’t figure out how to actually use it. Am I headed in the right direction? Does anyone have an example of a mapping from a multipartition? Thanks in advance if anyone has any guidance.

Thank you so much Claire!
