PO Payment Terms

I am looking for a clarification on the JDE standard functionality around setting the Payment Terms in PO header to BLANK.

Scenario:

Payment Terms:

BLANK = Net 30 Days

006 = Due Upon Receipt

In the Supplier Master, the Payment Terms-A/P of vendor 123 is set to “006” .

When I created a new purchase order for vendor 123, the Payment Terms on the PO header defaulted to “006”. I blanked out the Payment Terms and saved the order. When I
re-inquired on the order, the Payment Terms reverted back to “006”, which is the default assigned to vendor 123.

I then edited an existing order for vendor 123 and updated the Payment Terms to BLANK, then saved the order. When I re-inquired on the order, the Payment Terms remained BLANK.
