Does the lineage graph refer to the Atlan lineage or the Power BI lineage?
This is for the lineage you'd see in Atlan (for the related Power BI assets).
Are we able to hide these processes by default?
Currently, the process entities cannot be hidden in the Assets page.
What does the process below mean if it's lineage is blank?
These process entities don't have a counterpart entity in Power BI. Consider these to be nodes over which you can add some documentation/metadata describing the process or relationship between two Power BI assets. These become especially useful for SQL first sources like Snowflake, where these process entities will show the transformation SQL query that was parsed to generate lineage. This provides a way for users to easily discover source code/scripts.
