How to exclude extend products [child products] from sync process

[Former Member]

Hi,

I am trying to understand , what would be the good approach to customization sync rules for below scenario.

we have around 5 to 6 catalogs among them one catalog is master catalog where we will feed all products . Usually we will sync all products from master to other catalogs staged version. later we will sync each catalog from staged to online.

Catalog Sync rules

M - > A,B,C,D (staged) [sync rules] ,
A (staged) -> A(Online] , B (staged) -> B(Online) ------and so on.

let us say we have below products 1.Product... ChildProduct1 extends Product... ChildProudct2 extends Product... ChildProduct3 extends Product... -----and so on.

In order exclude childProduct2 type instances from sync process i.e. especially from M->B , what would be best approach?

Thanks In Advanced.
