In Business Central, you can’t “increase” an already posted sales invoice amount directly — a credit memo only reduces it. If you need to charge the customer more, you must issue a new sales document:
Sales Invoice → create a new invoice for the additional amount.
Sales Order (if order-based) → add a line for the difference and post.
