Hello Ludwig,
Sorry if i'm not explaining it in detail it but the invoice is made from a single PO but with multiple receipt
Previously the user already invoiced the PO but the amount came out just fine. but when they want to invoice it again the totals amount came out but when they check the subledger journal/accounting distribution is 0
so what they doing to make the invoices are
1. create 1 purchase requisition
2. release it into 1 purchase order
3. make multiple product receipt from 1 purchase order
4. make 2 invoice before this problem from that same 1 purchase order
5. then they create new invoice again using the same purchase order but the amount in subledger journal/accounting distribution is 0 but the totals amount is there
here's some screenprints but because of company privacy, i have to censored some few parts:
this is the totals

this is the subledger journal

this is the product receipt

this is previously posted invoice

this is the PO lines

if there's anything missing or you want another screenprints just let me know
thanks
