What's fixed

Tax Calc API: Credit invoice Gross Amount sign preserved as submitted (5804194)
Determination now preserves the Gross Amount sign exactly as submitted for credit transactions, regardless of how the IS_CREDIT indicator is set at the invoice or line level. Previously, when IS_CREDIT was set to true, Determination normalized all line-level Gross Amounts to negative values regardless of the sign originally submitted.
