Prevent users from editing the code combination at the invoice distribution level

Summary:

1.When an invoice line is selected with Line Type Freight or Miscellaneous, the system automatically derives the correct code combination based on the current setup.
2.However, users currently have the ability to manually edit the code combination at the invoice distribution level.
3.This manual change of the code combination by users is causing accounting discrepancies.
4.Based on our initial analysis, Oracle Fusion does not provide a standard configuration option to prevent users from editing the code combination specifically for Freight and Miscellaneous line types at the invoice line level.
