PBI Dataset Not Refreshed Due to Reaching Memory Limit

Hi MS Support & Community, For number of large datasets in our primary PBI workspaces, we have seen errors last couple days related to insufficient memory in premium workspaces.  How can we check me...

    Ensure you have Large Dataset turned on for the dataset sirahcy , and see this article. It specifically mentions a 12GB dataset in a P1 capacity might cause issues, but a 9GB may depending on what else is loaded at the time. Large datasets in Power BI Premium - Power BI | Microsoft Learn

    Are you using incremental refresh? The entire dataset does not need to be loaded during refresh if you are using incremental refresh on the large fact table(s). Only those recent partitions that would refresh.

    Thank you edhans.  Yes. We're enabled for Large dataset and incrementl refresh on the large fact tables.  Some of the datasets actually approached 12GB or exceeded so we definitely will look into sizing the capacity.  We're using incremental refresh (e.g. ~60% of a fact table), but not sure how much saving in  memory usage, instead of 2x dataset size using full refresh.
