Make the expense line unique on base items and Extended attributes .
Current Unique Item Combination = ( Year+Period+Expense Category+Description)
Requested Unique Item Combination = ( Year+Period+Expense Category+Description+ Extended Attributes )
Example: If we have a Expense line by Multiple Brand & Segments then in current set up the uniqueness is lost and we have to change the description with a suffix of 1, 2 etc but if we had the uniqueness with base items and extended attributes then we need not have to change descriptions to make them unique.
