Assuming the work location country of an employee is XX as of payroll Run date, and after payroll is completed HRBP entered transfer transaction with a retro date. This transfer transaction resulted into a change in country of work location.

So today if we try to get the location_id from per_all_assignments_m as of payroll run date and further join it to per_locations we may get the country of the work location that was entered with a retro date, but what if we would like to know the country that was used when payroll was run, do we have a table from which we can get this.
