Title
Check program for archiving billing documents

Purpose
This report checks whether an order can be archived.
Billing documents can only be archived if they have an actual billing
document or entry date (depending on the selection made on the
selection screen) that is earlier than the selection date.
Document flow is used to check that the billing document no longer has
any successor documents.
The system displays billing documents that can be archived in green.
Those documents that cannot be archived are highlighted in red and are
not displayed on this screen.
