Partial paid open AP invoice conversion with Payment schedule

Summary:
Partial paid open AP invoice conversion with Payment schedule

Content (please ensure you mask any confidential information):

We have an Conversion AP Invoice with Original Invoice Amount USD 1000 and Date of Invoice is 1-Jan-2025 with following Payment Schedule based on payment term

1. 30% in 1st Month i.e. 300 in 1-Feb-2025 ( This is paid)
2. 30% in 2nd Month i.e. 300 in 1-Mar-2025
3. 40% in 3rd Month i.e. 400 in 1-Apr-2025

Now when we are converting the Invoice with only unpaid amount, the payment schedule is getting calculated based on remaining amount of 700 USD which is incorrect. Payment should should contain only 2 schedule i.e. installment 2nd and 3rd from above.
