User cannot Display Purchasing Contract on Fiori

[erene]

Hi dear Experts,

I want to approve purchasing contracts on Fiori (like I do on ME35K tcode) but I have a problem on displaying purchasing contracts on Fiori. As soon as I open my inbox app on Fiori, I see an error pop-up. Agent assingment is done and SAP version and roles on user are as follow

Is there anything i miss on diplaying contracts on Fiori for approval, could you please help.

Thanks
