In the Process when you apply for example vendor ledger entries (Payment --> Invocie), you can run the action "Preview Posting"

in this Page: Detailed Vend. Ledg. Entries Preview (P129) - it is not possible to save the Filter. Or when you save the Filter and apply the filter the page will always be empty. If you use the temporary filter it works fine.

This change would be very helpful for many of our customers.
