ESS Leave request issue for Two level

Dear all,

I am using standard workflow Template WS12300111 and enhanced it for 2nd level of Approval.

Gone through this wiki Customizing the ESS Leave Approval using Business Workflow - ERP Human Capital Management - SCN Wiki and done the coding as mentioned.

But my issue is after 1st level of Approval, not able to clear it from his Worklist. So, Both the approvers are able to approve the Leave request. Please help me with your inputs.

Thanks,

Srilatha
