My Inbox - /IWPGW/TaskProcessing (v2) - TaskCollection is Blank

Experts,

I need your help in getting to bottom of this and finding the root cause. I am facing challenges in loading tasks in My Inbox app. My aim is to show all workitems from the SAP Inbox.

I have 10 workitems in my SAP inbox (SBWP). I can see them as part of my PO and PR approval apps, but they don't show up in My Inbox App. What am I missing?

LaunchPad -

Service Configuration -

System Aliases -

Scenario Definition -

Service Document -

TaskDefinitionCollection Set -

Scenario Collection -

But TaskCollection is Blank -

What did I do wrong? Please help!

Thanks,

Rohan
