Rate definition is taking FTE from position rather than from assignment
Derived rate definition contributor has the box ticked to return FTE value. But the value is being prorated up by the position FTE, rather than the employee's assignment FTE.
Employee is in a position which is 40 working hours on 40 standard hours, i.e. full time, 1.0 FTE
However, the employee's assignment has position sync flag disabled, and at assignment level the employee is working 20 working hours on 40 standard working hours, i.e. 0.5 FTE (jobshare). The salary basis holds their actual salary, i.e. half the rate of a full time worker.
We have an element rate definition that retrieves the salary basis value (part time actual amount) and has the "Return Full-Time Rate" ticked, so this should return the salary that a full-timer would receive
