Is it possible to change the order of the columns or delete a column not used in customer maintenance under the invoice tab We never use the Disc Date or the Discount amount is it possible to move them to the last columns or remove them from the view…

I would like to know how to add a custom field that is listed on our sales order entry screen to the Customer Maintenance/Customer Inquiry tab 6. Invoices screen as a column next to the Customer PO No. column. Is there an easy way to do this myself?
