Cascading and Cumulative Discounts on pricing promotions

Hi Team,

We have a requirement where an item has a list price of 100, and we are applying attribute-based discount rules and Pricing Promotions

First want to apply discount rule: 10% discount (100 − 10% = 90)

Second need to apply Pricing Promotions: Another 10% discount should be applied to 90

Currently, the second Pricing Promotions is being applied to the list price (100) instead of the adjusted price (90). We want the second Pricing Promotions to be applied to 90, which is the result after the first discount rule.

Please help us achieve the above requirement.
