I have a parent material "x" having a component "y". Both are in house manufactured materials and having shelf life and expiry date. Now my requirement is that the expiry date of the "y" should be the expiry date of of"x". How can I achieve this. Can anybody help me on this.
Eg
Material: "y"= expiry date =10th Oct 2014. - Batch A
Now I am using this batch " A" of "y" to make "x" and this "x" should have an expiry date - 10th Oct 2014
