When working on the sell screen, you may sometimes see items on the sale that are locked. These locked line items will have a small padlock icon on the right of the sales line, making them uneditable.
A line item may be locked due to:
1. Layby, on-account or partially paid unfulfilled sale: if you process a layby, on-account sale, or partially paid unfulfilled and reopen this sale at a later date, the line items from the original sale will be locked. You can add new items, complete the sale or void the sale. However, you cannot remove any locked items from the sale. If you wish to remove items from a layby, on-account, or partially paid unfulfilled sale, you will need to void the original and recreate the sale.
2. Custom integrations/API: the line item may have been added to the sale automatically as a "confirmed" transaction in order to prevent any further adjustments. This only occurs if your store has a custom-built integration using our API. If you are not sure if your store has a custom integration, ask your store manager or owner.
