3733779 - No rejection email when 'restart workflow' is used in supplier invoice workflow

When a supplier invoice is rejected in flexible workflow with the rejection action set to "restart workflow", the configured "request was rejected" email notification is not sent.

SAP S/4HANA Cloud Public Edition

1. Create a supplier invoice and submit it using Save as Completed.
2. An approver rejects the supplier invoice.
3. The requester does not receive the configured rejection notification email.

Email notifications for rejection are dispatched only when the workflow reaches its end; with the rejection action result set to "restart workflow", the workflow does not end, so no rejection email is sent by design.

Review your workflow’s rejection action result and notification settings. If an email on rejection is required, set the rejection action result to "cancel workflow" so the workflow ends and the rejection notification is sent.

If the business requires resubmission after rejection, keep "restart workflow" knowing that a rejection email will not be sent while the workflow continues. 

The rejection email while using "restart workflow", would be a new functionality.
