Hi Team,

Recently we had a requirement to check Item description duplicate. Let me put scenario and explain in brief

Scenario: We have an item class with few attributes (EFF). These few attributes are part of Item creation in "Create Item" Page and meant to define the item description by concatenating its values. So an "Assignment Rule" is created to derive the description from these EFF's so that these fields come as mandatory while creating item in Item Creation page in Product Development (PD).
