UWL Tracking Tab in Portal

Hi KM Gurus,

Could anyone tell me how to get information about an EBP PO status in the tracking tab of the Portal's UWL?

The tracking tab does get populated when a Leave Request is sent through the approval workflow.

However, none of the approved, rejected or completed workflows are reported in the tracking tab.

Your help will be greatly appreciated and suitably rewarded.

Thanks & Regards,

Vibhu
