Issue with receipt accounting-Country segment not derived

Summary:

We are facing an issue in Receipt Accounting.
While reviewing the transaction in Review Receipt Accounting Distributions, the accounting is failing due to a Cross Validation Rule (CVR) error.
We verified the SLA Account Rules and Cross Validation Rules.
As per the current SLA setup, the system should derive the Country segment value from the source, but the system is not picking the expected country code.
Instead of deriving the correct country code, the account is getting generated with 000, which violates the CVR rule.
As per CVR rule, for the given natural account range, the country segment must follow the defined validation rule, but since the system is deriving 000, the transaction is failing during receipt accounting.
