Issue:
An issue arises in NetSuite where customers cannot be changed on invoices that are created from sales orders. This limitation does not affect standalone invoices, where the customer field remains editable.
Cause:
This behavior occurs because the Invoice Groups feature is enabled in NetSuite.
This restriction occurs regardless of whether the “For Invoice Grouping” checkbox is selected or not in the transaction or customer record.
Solution
. Disable the Invoice Groups Feature:
- Go to Setup > Company > Enable Features.
- Under the Transactions tab, locate and disable the Invoice Groups feature.
- Disabling this feature will restore the ability to edit the customer field on invoices created from sales orders.
Note:
It is not possible to disable the feature if there are any entities or transactions that make use of the group invoice feature.
