There are cases when saving a Sales Order returns a message “An error occurred while processing Line Items.” One possible reason is a custom line field that displays an error message “Error: Field Not Found”. To resolve this, the custom line field has to be checked if it has a formula sourcing a value via a valid {id}.
Solution
- Navigate to Customization > Lists, Records, & Fields > Transaction Line Fields
- Preferred Custom Field: Click Edit
- Store Value: Remove Checkmark
- Click Validation & Defaulting tab
- Formula: Verify if the Formula is referencing a valid {id} of an existing field
- Click Save
