How can we avoid copying of an EFF Value from KIT Line to Included Line in a Sales Order

Hi Experts,

We have created an EFF at Sales Order Line Level for storing order quantity to perform few validations in Order Management Extension.

Whenever we update any EFF Value on KIT Line every EFF value including the newly created are being copied to Included Lines. Is it possible to avoid copying of these EFF to Included Lines and retain their current values.
