Find closest date

[Mark.rooker]

Morning

My 1st post on here, so please be kind!

I am trying to find a way of pulling in data based on matching the closest lower date.

I have 2 tables:

Employee_Bookings that holds all the Time & Attendance of our employees and includes the following columns:
Emp_No
Date
Time_in
Time_out

Effective_Rate that includes the employee rates of pay and when that became effective and includes the follwoing columns:
Emp_No
Eff_Date
Rate

What I am trying to do is get the employees rate of pay at Employee_Bookings.Date by finding the closest lower Effective_Rate.Eff_Date

I hope that makes sense and someone will be able to point me in the correct direction

You could use a >= join FROM the Employee Bookings table TO the Effective Rate table on Date to Eff_Date, with an equal join on the Emp_no field. This will return potentially multiple eff_dates per employee. Insert a group on {Employee Bookings.Emp_No}.

Then go to report->selection formula->Group and enter:

{Effective_Date.Eff_Date}}=maximum({Effective_Date.Eff_Date},{Employee_Bookings.Emp.No})

This will return only the row containing the most recent rate.
