Relationships when values do not exist in both tables

[snack]

Having trouble correctly creating this relationship.  Here is my situation.

• Both tables have a field "Email" that contains unique values.
  • Table "Staff" - every employee
  • Table "Staff_Training" - only employees who completed training
• I would like to retain all entries in the "Staff" table, as it will serve as a lookup table for other data I will bring in.  This way I can represent information, such as, "% of total staff that completed training".

What would the correct way to create this relationship be?

Hi @snack ,

I think this scenario not suitable to use relationship. You need to manually calculate these instead to use relationship.(some of records not existed in table, so they can't mapping to raw table)

For this scenario, you can consider to use except function to extract untrained employees to calculate.
