Deleting IT0015 Retro Issue

Hello,

We have created a payroll rule to calculate tax based on the WT entry in IT0015 and specific tax rate constant. Basically the rule includes the following:

ZZZZ

VWTCL 99

1

1234 ABC Award

ADDWT *

AMT%KZONSO

ADDWTE/301

AddWTE9108 AMT*-1

ADDWT /110d

Everything works correctly. However, if we have to delete this wage type entry (after being processed by payroll) due to a keying error we run into an issue. When retro runs the employee's net pay is correct. However, the WT9108 amount does not reverse. I would assume it is because it is no longer hitting the rule. I tried reversing the amount and it bombs in payroll. Any suggestions on how to handle this scenario?

Thanks!
