ax 2009 workflow approvals

[Kent]

Hi,

I have workflow template with two Approvals. Example, SalesApproval(first step) and PurchApproval (second step).
Template property CompleatedEventHandler has class with method, example "Compleate" where I can update my ApprovalStatus or something else. How can I known, which Approval (SalesApproval or PurchApproval) called this method?
Or should I create separate classes for each Approval and set this classes for needed Outcomes (Approve, Deny,etc.)

Thanks.
