Rahul,
I thought the discussion was about stock?
Product doesn't 'belong to' a work center, so there is no such Icon. Neither does stock belong to a work center.
Work centers are used in production orders/planned orders. A single order can contain many work centers. A single product/location can be built using multiple PPMs/PDSs, each of which can have different collections of work centers.
Best Regards,
