This is a feature gap that denies the customer from supporting his business scenario. He wants to the "Requester" to be the "First Approver" in the purchase order workflow. Currently, it is only allowed to choose the requester as the starting point for the hierarchy's approval, but he is unable to approve the workflow.

For example, in the Dynamics 365 Finance update from April 2024, there is a feature that allows the purchase order's requester to be added as the invoice approver in 10.0.33. This means that the requester can be involved in the approval process right from the beginning, ensuring that any discrepancies or issues are addressed promptly.
