Asset creation issue

While making a purchase receipt with an item having many quantities, after submitting, asset created with a sum of all the quantities in a single record. like: if I purchase 3 chairs each $50 and if I submit, then only one asset would be created with the value of $150 but it should create 3 assets instead like chair01, chair02, chair03 each $50.

You can create 3 lines in your receipt, each with quantity 1. That should help you.
