Odata service for My Inbox - Approve Purchase Order not found error

Hi all,

We have configured the application My Inbox - Approve Purchase Order in S/4 Hana and we are able to see the tile . But on clicking the tile , we get the error that service /IWPGW/TASKPROCESSING 002 is missing. As per the Fiori Apps library documentation , the following odata services and the backend PFCG roles are required

When i checked my SAP system , I found both the services C_PURCHASEORDER_FS_SRV 001 and /IWPGW/TASKPROCESSING service in my system. But I am getting error /IWPGW/TASKPROCESSING 002 is missing. The service TASKPROCESSING is active and also System ALIAS is assigned.

Thanks & Regards

Amber
