With the implementation of AYP, if an 18F employee has a supplement the position in which the employee is seated will need to have the supplement earnings code specifically funded.  If the supplement earnings code is not funded the supplement amount will not be encumbered – only the contract amount will be encumbered.  MSS System Managers will need to know the employee’s supplement Comp Rate Code and can then use this ‘mapping’ document to get the appropriate earnings code that will need to be funded.
