# Compute rate per hour

• ### Question

• Hi,

I have 2 simple tables.  The first table is named Employees and second one is named hourly_rate.  I have created a relationship from the Grade column of the Employees table to the Grade column of the hourly_rate table.  I now want to create a Pivot Table dragging Names from the Employees table and rate per hour from the hourly_rate table.  I wrote the following calculated field formula but the result I get is 21 for all employees.

`=SUM(rate_per_hour[Rate per hour])`

Also, in the Pivot Table field list section, I get a message saying that "Relationships between tables may be needed".  There is already a relationship between tables so why do I get that message.  Please note that I do not want to create spare column in the Employees table in the Data model to first bring over the rate per hour from the hourly rate table.  I am looking at directly writing a calculated field formula for the same.

• All relationships are one to many. Your grade table is on the one side of the relationship. The employee table is in the many side. Filters automatically propagate from the one side to the many side - not the other way around. As a result, employees will not Filter rate automatically. This formula will work. =calculate(sum(rate[rate]),EmployeeTableName) But this is very complex dax.
