When entering a document in Attaché the screen design can be customised, There is a Print? field that is available to place on all documents that affects how documents print.
To check why a document line is printing or not:
Go to document lookup, for example: Customers, Transactions, Invoices, Look up
Using the above example: Enter the Customer Code and select the Invoice Number using F2 Find or go straight to the Invoice Number field and enter the invoice number.
The Print? field may or may not be on the line summary screen depending on your screen setup. If you cannot see the Print? field use F8 Zoom In to check the Zoom In screen for each line. If you still do not see the Print? field you may need to edit the Screen Design to add the Print? field.
Screen Designer is accessible, continuing with the example, under Setups, Customers, Screen Designer, but is similarly placed and available for other modules as well.
If you do not see the Screen Designer menu you may not have Menu Access Rights to access it. Check with your Supervisor.
A line will print if the Print? field is ticked.
With some documents, for example an incomplete Sales Order, you may be able to change the Print? field, if the line has not been completed, so as to print the missing line.
If you cannot edit the document's Print? field you will need to reverse or cancel that document and then replace it. For example, a Sales Invoice once created cannot be changed, so it would need to be credited and re-invoiced.
