Milestone Tax - Receivables

Hi,

We are building a milestone billing solution which creates an Invoice then imports it to Receivables via Auto Invoice. 

Ideally as the tax requirements vary we are allowing users to the ability to allocate a tax status code against a milestone and when the Invoice is loaded into AI the tax regime to Rate details will be entered.

We are not creating a TAX line but just populating the Regime to Rate data against the Line Type = LINE.

When AI runs it ignores the pre-populated Tax Regime to rate data and the tax is assigned as per the ebTax rules.
