When I try to refresh the Semantic Model behind a report, I get the following error;
"Unable to save the changes since the new dataset of size 1484 MB exceeds the limit of 1024 MB. If the dataset is hosted on a PowerBI Premium capacity, you may also reach out to your capacity administrator to see if the limit can be adjusted."
However, When I view the report size (Cog Icon>Manage Group Storage) it shows the report as being 386MB. The report seems to work fine, with data that is largely current. How can the refresh, which will only be pulling through a small proportion of additional data, be increasing the size from 386mb to 1484mb?
Assuming that the dataset really is that big, I've seen this page with recommendations on how to slim down the size of the data. How can I see whaich of my tables are the largest, so I have a chance of making impactful changes?
