How to include Fiscal Classification in Price Sales Transaction REST-API

Hi,

We are using 'Fiscal Classification Type Code' on Customer Profile for acknowledging tax rules, when trying to get the same tax rule within 'Price Sales Transaction' with relevant Customer attributes, we cannot achieve the same tax calculation which is based on 'Fiscal Classification'

While in the sales order itself, the Fiscal Classification is take into consideration.

/fscmRestApi/priceExecution/documentPrices/priceSalesTransaction

Can you help us on PST REST-API to include Fiscal Classification to be consider?

Regards,

Dor
