IBP Disaggregation expression

Hello,

can i use attributs values in the copy operator? example.

I have a product group with 5 product. 2 of this products have an active status. this status is managed in the product md type in an attribut called active. all active products have an "X" in this attribut

Now, the disaggregation should only consider the products, which have an "X" in this attribut.

How can i this solve.

thanks in advance

Oliver
