I have an issue when using BSFN X00TAX Tax Amounts Calculate - CalculateValidateTaxAmounts

When I call this business function via an application, the tax, taxable amount are correct but when calling from a UBE the tax and taxable amount are rounding and excluding the cents.

Why would the results be different?

For example results from application

From UBE Tax = 989.00 and 13559.00. I used the same data dictionary values

another example

From UBE Tax = 84.00 and 646.00. I used the same data dictionary values

Also deployed the changes to the web and get the same results. The UBE is rounding excluding the cents.

I want both the application and UBE to be consistent.
