Power BI - relationship ambiguity

Question

• I have two fact tables which I would like to connect to a dimension table (this dimension table is connected to a further dimension table).
• When I try to activate the second connection, I get an error message that this would create ambiguity between the two fact tables and that I should delete the connection between the fact tables.
• The fact tables are not connected (no relationship between them)

How can I resolve this? It almost feels like a bug...

Answer 1

Solution:
Step 1: Change the relationship to fact table #1 to single direction and close relationship window so that the change materializes.
Step 2: Active second relationship between fact table #2 and dimension table.
