What are the appropriate steps to take to change the GAU on an Opportunity? I've tried reallocating to a new GAU, but because it is associated with a Payment I am getting this error: "Error: npsp.TDTM_Allocation: execution of AfterUpdate caused by: npsp.ALLO_PaymentSync_SVC.PaymentSyncException: The total allocation of paid payments cannot exceed the opportunity allocation for a GAU. (System Code)"
