So I have made some invoices in which the "invoice date" does not match the "accounting period". In a journal you have option to check the dates but that isn't right now important.
What I need to do is a tree view which shows entries that accounting period is not in the same month as invoice date. How would I do it? I researched filters but I am not sure how I could make so complex filters. Another thing I saw was SQL queries but again I am not sure how I could attach the data to tree view.
