FDBI upload issue in Payable Invoice

Summary:

When invoices are uploaded through the spreadsheet, the system allows us to enter any numeric value in the Attributes section at the invoice line level. Even if the entered attribute value is not available or listed in the system, the invoice is still accepted without displaying any validation error.

Expected behavior: The system should validate the attribute value against the values configured in the system. If the entered value does not exist, it should display an appropriate error message and prevent the invalid value from being accepted.
Actual behavior: The system accepts the unlisted/invalid attribute value without showing any error.
