Item Description Generation Rule - Attributes to be Non-Mandatory

Summary

Item Description Generation Rule - Attributes to be Non-Mandatory or generate Item description with available attributes

Content

We are using Rule Sets to generate Item Description Based on User Defined Item Attributes.
E.g.) In Case of Couplings we are using Material, Outside Diameter and Length of thread to generate Item Description

We have defined the Item Attributes and Item Rules for concatenation of Item Attributes to create Item Description. The rule is working fine and Item Description is getting generated as expected.

However when we create the Item all attributes included in Rule for Generation of Item Attributes become mandatory.
