Tax calculation based on Prior period date

Summary:

Dear Experts ,

We have a requirement where VAT rates will change on a specific date. When this happens, we will have L&M jobs that have been finished before effective date, but will be invoiced after the effective date. In order for the tax engine to consider the correct VAT rate, the (performance date ) when the services was provided in prior period must be passed from ServiceMax to Fusion ERP for tax calculated on prior period date before the VAT changes .

One of our integration for AR invoices is from ServiceMax .

Service provided - 01-May-2025
