Currently in Microsoft Dynamics 365 for Finance and Operations, there is no list page for expense line level approvals which makes it a time-consuming activity for approval of all lines from different expense reports.
This enhancement shows all the expense line level documents pending for approval in one list page to execute the workflow actions. Approvers can see a list of expense lines assigned to him\her in one view and take action. This feature is not a parameter driven.
Thanks for your feedback.
