Reporting on course of time - supplier invoice-approval task

Hi,

we are looking for a possbility to follow up the times (duration) between

• scan of a supplier invoice and manually extending the data in ByD
• the manual modification (last change date) of the document and the posting
• the times between each approval task

The reason for this request is to optimize our internal processes. Can you think of a possiibility to do this without development?Kind Regards,Klaus
