As of Release 4.6A, the ABAP List Viewer (ALV) is used to output the log for the invoicing plan: you can create and save variants for the log output and maintain your own settings in them.
On the log output screen, you can display the following environment information for analyzing the invoice items: purchase order and long text.
The Simulate function has been extended: In test mode, the system checks if the invoice can be posted.
