General Auto Complete Question on Overwriting a rule

Hi All,

Is there any ways to insert a way to overwrite an existing Auto Complete Rule if HR enters a value?

For example, my current logic is IF termination date is entered, AttributeDate1 (Access End Date) = Termination Date. However, if HR enters a different date, it does not overwrite the rule logic and reverts the Access End Date back to Termination Date when submitted.

i.e. Termination Date Oct 1, AttributeDate1 becomes Oct 1, but HR changes AttributeDate1 to Oct 31. After submission, AttributeDate1 becomes Oct 1 again.

Any ways to make AttributeDate1 stay as Oct 31 in the example above?

Thanks,

Steven
