How to read custom settype attribute from product/item

Hello everybody,

I created a custom settype and assigned it to a category in transaction comm_hierarchy. THe settype contains just one bool attribute.

In transaction I created a product and set the value for this attribute.

I added this produkt to an existing order in CRMD_ORDER.

In genil model browser i found the standard relation and attributes for the product (BTItemProductExt) but I can't find the custum attribute.

I need to get the information of the custom attribute in ABAP. How can get it?

Thx in advanced and BR
