The GANI (Goods Accepted Not Invoiced) is where goods go that are awaiting an invoice from the supplier of those goods.
There's a number of reasons postings appear here.
1. Parts are brought into stock on a Goods In note.
2. Sub contracts are posted via the service department.
3. A Delivery Note reference is entered instead of an Invoice Reference.
4. No invoice number is entered when posting against a deal.
5. The staff record doesn't have "Direct Posting" ticked.
