How to consume points prioritizing those closest to expiring in Power BI?

[stiven965]

I have one table with these columns:

ID

Name

Date

Points

ExpirationDate

Each record represents the points earned by a person on a date, and has an assigned expiration date.

I also have a second table with the amount of points to redeem for each user.

For example, Juan has 50 total points earned on different dates. Juan wants to redeem 50 points for a prize that costs 27 points.

I need the consumption of the 27 required points to be done by prioritizing Juan's points that are closest to expiring.

How can I create this logic in DAX? I thought about previously sorting the table by ExpirationDate and then making a cumulative sum with filters.

But I'm not sure how to implement the necessary filters to respect the logic of prioritizing by expiration date.

I appreciate if someone can help me by providing an example or pseudocode of how to create this measure in DAX.

Thanks,
