How to Update BPA Supplier Item column to Blank(NULL) using FBDI?

Summary:

We are trying to update supplier item to blank(null) using POBlanketPurchaseAgreementImportTemplate.xlsm

I refer to the following notes

How To Update Fusion Value To Null Via Customer Import FBDI? (Doc ID 2496299.1)

PRC: POZ: How To Pass Null (Blank) Value In FBDI Field For Supplier (Doc ID 2718519.1)

But no matter I enter'#NULL' or '!'.

The column gets sync with '#NULL' or '!'.

Please advice.
