BADI PT_ABS_REQ Not updating approver in ESS portal

Hello,

I'm implementing Workflow WF33700137 for multiple level approvers for ESS leave application. I have implemented method GET_MULTIPLE APPROVERS in BADI PT_ABS_REQ to get multiple approvers. But the approvers that I pass in the BADI do not show in the application. Please let me know if I miss any output parameter in table ET_APPROVERS or in the method.

Thanks
