I have a question about assigning items to multiple categories in an online hirerarchy.
If we go to the released products form and to the "Product categories" form we are able to assign the product to multiple categories in the same online navigation hierarchy.
When we go to Retail -> Setup - Category hierarchies - Retail channel navigation hierarchies we can see that the item was indeed added to multiple categories so it is the same table.
However, if we now try to add an item to multiple categories using this form, the system throws an error: "Product X is already assigned into hierarchy Channel navigation hierarchy."
Is this an oversight and the check is not working in the first form or is it something else?
