[fivetran-avinash]

PR Overview

This PR will address the following Issue/Feature: Internal ticket

This PR will result in the following new package version: v0.3.2-a2

This changes variable configuration logic but the field column values remain the same.

Please provide the finalized CHANGELOG entry which details the relevant changes included in this PR:

This pre-release introduces the following updates.

Bug Fixes

• Modified the variable logic in zuora__using_multicurrency in these models so that the *_amount values are called by default rather than *_amount_home_currency when the variable isn't configured:
  • int_zuora__transaction_grouped
  • zuora__line_item_history
  • zuora__monthly_recurring_revenue
• Single currency is now the proper default and multicurrency customers must leverage the variable to enable that functionality. (#21)
