Dear
when i go to invoice a sales order i am getting the below error
either if i go to Account Receivable >> Periodic >> Sales Update >> Invoice
or if i go to the sales order itself and invoice it i get the same error
Cannot create a record in Sales order - update (SalesParmUpdate). Document status: Invoice.
The record already exists.
apparently this is an invoice sequence number, which one should i look at to solve
regards
