AP invoice creation via spreadsheet got rejected due to "Invalid Supplier" error

Summary:

We have a supplier in place (for e.g. 23C Test Supplier) and if we try to raise an AP invoice for the same using spreadsheet by giving supplier name in upper case i.e 23C TEST SUPPLIER it keeps on failing at the time of import by stating "Invalid Supplier". May I know how to ignore supplier name case sensitive validation rule at the time of importing invoice in Fusion if any.
