An employee’s work study award balance appears to have a negative balance. Can I submit a ‘Re-Apply WS’ Salary Cost Transfer?

Yes.  The ‘Re-Apply WS’ option will first unsplit the earnings in the transaction, crediting the award, and then, with the new award balance, attempt to re-split the earnings. If the award balance is positive after the award is credited, it will result in a split (W, D) or a partial split (P, S, Y). If the award balance is zero or negative after the award is credited, it will result in split refusal (X).
