The information from the Supplier Invoice populates the Entry when it is prepared. The information cannot be updated directly in the Entry screen. Any changes required to the Entry must be made in the original Supplier Invoice.
Expedient provides some shortcuts to updating multiple supplier invoice lines quickly where the prepared Entry is consolidated.
Where Supplier Invoice lines have the same Sub No and Entry Line number, in Update mode invoice lines will be highlighted as a group.
If you want to make a change to the whole group, for example change the TRT, Country, Preference or Preference Rule ensure the General Edit button is on.
Then Click into the column on one row that you want to change. Make the change then click the relevant Update button at the bottom of the screen, e.g. 
. This will apply the change you made to the single line to all the lines within the highlighted Entry Line group on this invoice and any other invoice lines for other invoices for the job that are consolidated to the same Entry Line Group.
The cursor must be in the correct column to action the update. Mass updates available are for the following columns in the Supplier Invoice screen,
- Treatment
- Country
- Preference
- Preference Rule
- P.O. Number
- Additional Info
The 
button works in a similar way. Update the Codes on line in the Entry Line Group and press this button to apply the update to all the other Supplier Invoice lines in the Job that have been consolidated to the same Entry Line Group.
When you have made the change the Supplier Invoices remember to go back to the Entry screen and click 
then 
to pick up the amendments from the Supplier Invoices.
