Limitations of Standard Workflow Possibilities:
- NetSuite does not provide a Confirm (Warning) action for sublist items after adding each item or before submitting the record.
- If we use the Return User Error action before submitting the record, all entered details will be lost since the error message appears in a new tab. Additionally, it is not possible to highlight or notify which specific line item has a zero amount.
Note: By default, NetSuite displays a warning message when the unit rate of an item does not match the amount based on the assigned price level in the item line.
Alternative Solution:
- Explore scripting options to trigger a warning either after adding a line item with a zero amount or before record submission, highlighting the zero line items.
