User often receives old purchase invoices. They wish to post the invoice to the current period , but want the date on any vat reporting and on reports and enquiries within the purchase ledger to be the actual invoice date. I am aware of the parameter use document date for vendor invoices , but with that ticked it will update the ledger as at the invoice date ( which they do not want) unticked the date in all standard vat enquiries and reports such as statement of account will show the posting date . This is a UK setup. Do you have suggestions how to handle old purchase invoices in the way they require
