SAP Fiori Timesheet Approval Error II

Hi,

We have successfully setup a Fiori Timesheet request application, but we when we try to approve timesheet entries the approval was not sent to the backend.

We can submit the approval, but once the submission is complete, the list was emptied by the application and prompts success.

When we click back to the application (Approve Timesheets) via Fiori Launchpad, the entries still exist and the changes are not reflected at the backend.

There are no errors from the browser or from the /IWFND/ERROR_LOGS, and all approval/rejection are working from the back-end side

Thanks.
