Hi experts,
Invoice against billing date in the closed FI posting period still can be created or cancelled. U know, even invoice can be created or cancelled, the corresponding accounting document cannot be generated. It seems meaningless to allow the first step, i.e. to create or cancel invoice.
Q1. Why invoice still can be created or cancelled? What's the logic or purpose?
Q2. Is it the standard reaction in SAP?
Q3. If yes, is it the only way to use user exist to disallow the first step?
