After a repre response is accepted, denying for merchant credit errors out on transaction selection with the message "This credit has been applied to this dispute"

1. After a repre response is accepted, denying for merchant credit does not error out with the message "This credit has been applied to this dispute".
2. The validation will not allow you to move forward until you have selected credits equal to or greater than the remaining recovery amount plus ChargebackFXLossAmount Amount and less ChargebackFXGainAmount Amount.
3. If you selected Merchant credit is equal to or greater than the remaining recovery amount plus ChargebackFXLossAmount Amount and less ChargebackFXGainAmount Amount, and you select another merchant credit, you will see the message "This dispute already has fully applied merchant credit(s)."
4. The validation is present at both review representment assignments in the  MCReviewRepresentment flow (before and after PreArbitrationAttemptDeadlineDateTime expires)
5. Multiple merchant credits applied across the same dispute work as expected.
6. Multiple merchant credits applied across multiple disputes on the same claim work as expected.
7. Bulk processing of representment received works as expected.
8. Agent processing of Merchant credit works as expected.
9. Deny works as expected for a user for merchant issued credit.
10. Deny works as expected for a user on non merchant issued credit.
11. Deny works as expected when the system kicks off deny debit date automation
12. (regression) All other merchant credit scenarios work as expected. 
13. When a repre response is accepted and the claim is denied for a full merchant credit the dispute amount is not adjusted.
14. When a claim was denied for a full  merchant credit, the claim can be reopened and the dispute amount is as expected.    
15. (regression) Outside of the Accept Repre Flow: When a refer decision results in a merchant credit check, and a partial merchant credit is identified, users have the option to deny the remaining amount.

Resolved an issue where when a Mastercard claim received a representment response and it was accepted by the user and they chose to deny the claim for a deny reason Merchant Credit an error message was displayed "This credit has been applied to this dispute". This fix ensures that when a representment response was received and the user is selecting to fully accept the response and deny for merchant credit, the credits must be equal to or greater than the remaining recovery amount. If a user selects a credit less than the remaining recovery amount a message will display to the user to go back and partially accept the representment response with a merchant credit. Additionally, validation exists to ensure that if a credit is selected that is greater that or equal to the remixing recovery amount and the user attempts to select another credit a message will display "The dispute already ahs fully applied merchant credits.'

As a system, Reg E PC 10 vs Reg E PC 20 should be calculated based on the most recent (newest transaction) to ensure we are erring on the side of caution.

1. When a claim is initiated with disputes within the first 30 days and disputes outside of the first 30 days of account opening, Reg E PC date is calculated to 10 days.
2. (regression) When a claim is filed with disputes that only occur within the first 30 days of account opening, Reg E PC Date is calculated to 20 days.

Updated the Reg E 10 vs Reg E 20 Provisional Credit logic within QFD to provide consistency and ease regulatory compliance. Prior to this change, if a cardholder initiated a mulit-dispute claim with some disputes occurring within the first 30 days of a new account opening and other disputes outside of the 30 days QFD extended the Reg E provisional credit review to 20 days. The review was performed by looking at the earliest transaction date to determine if the claim qualified for Reg E 10 PC or Reg E 20 PC guidelines.

As a user, I should have the ability to split liability between deny and write-off.

Reported issue: When attempting to apply a partial merchant credit through the disposition node for the review representment assignment, the system is advising the full provisional credit amount is due to be debited instead of the partial disputed amount. As a result, we cannot deny for partial merchant credit and write off the remaining balance.

1. An option is available in the Review Representment assignment that allows the user to reduce the remaining dispute amount for any merchant credits identified.

Added the ability for users to accept partial merchant credits from the Review Representment assignment, which allows users to reduce the remaining dispute amount for any credits identified. When users have a Review Representment assignment they are able to select the ellipse to "Accept with Partial Merchant Credit". Users then have the ability to split the liability decision to write off and customer liable.
