I am trying to clear the create purchase invoice screen from all of the purchase invoices that are outdated.
The items on the list under the option Create Purchase Invoice are timesheets with a pay element which has not been processed. If you do not wish to process the timesheets and create the invoices then the process will be to remove the pay element of the timesheet.
The Ref on the Supplier Payment is the timesheet reference make a note of this.
The next step will be to edit the pay element of the timesheet through Timesheet Display. To expand the costing rates to show the pay rate select - Show complex rates.
and then remove the pay element rate by selecting the delete button
Then select Update which will give you an validate error, to override this error select Override. The timesheet amendments will then be saved.
