- Some of the line items invoiced have the incorrect actual cost noted.
- You want to change the cost after it has been invoiced to avoid having to credit and rebill.
For posted Sales Documents, it is not possible to modify the value directly on the Sales Invoice. In this case, it is necessary to return the item with the incorrect cost using a Credit Memo.
It's important to note that the details of the item in the Credit Memo must match the details in the posted document, including the incorrect cost.
After the Credit Memo is created, effectively undoing the line item in the journals, you may invoice the item again at the correct price. This additional invoice can be done by modifying the original Sales Order or creating a new one with the correct customer information.
