hello based on what you sent , it seems you have duplicates therefore , a many to many relationship , but it seems you have a duplicate in your dim salary table

so maybe just remove duplicates or create a new table 

Values = VALUES(dim_salaries[id])


here is your duplicate

Thats weird did you select all columns and pressed remove duplicates? Maybe you have the same id but it has different dimensions in the column
