Subinventory DFF Date type has an empty Table Column dropdown, blocking setup.

While creating a Subinventory DFF with the data type set to Date, no data appears in the Table Column dropdown list, which is preventing us from proceeding. The client requires the field to use the Date data type, but when we select it, the table column remains blank once the dropdown is opened. We have defined the DFF under the global segment. In reviewing the subinventory DFF configuration for INV_SECONDARY_INVENTORIES, it appears that the Date data type cannot be included. What could be the solution for this?
