Prevent table from loading after Power Query apply changes

[asaetrang]

Hi,

When I add a new table in Power Query through a dataflow and apply the changes, it does not only load the new table but also loads my existing fact table even though I haven't done any changes to that. The loading time is therefore increased significantly since the fact table contains almost 2 million rows. Is there a way I can prevent this from happening?

I have tried to disable "Include in report refresh" without any luck, and disabling "Enable load" is not an option since this table is basically the base of the report.

Thanks!

And you can consider to reduce the size of the data model to improve the refresh speed, you can refer to the following link.
