Hi. here's the scenario.
A billing document has been creating in transaction VF01.When created, an accounting document and a controlling document have been generated(you can get the document numbers when you click on the 'Accounting' button in VF03 or through FB03).
A cancellation has been carried out for the billing document (transaction VF11). However no accounting documents have been created for the cancellation.
Any idea on the customising which was missing?thx.
