Using Views for Validation Entity under Interface Attribute Definition does not work

Hi community,

We are creating a custom integrator to load purchase requisitions using a Procedure Type Interface integrator.

When defining the interface attributtes, we use a validation Type as Table and assign a View for the validation Entity, but No values are returned when entering data in the spreadsheet, the list of values is empty (when double clicking in the cell the pop up window opens, but no list of values are returned).

On the other hand, if we change the validation entity from View to a Table (that no setting context is needed), then list of values from the table can be seen under the spreadsheet.
