During activation of SAP Best Practices for SAP S/4HANA (for USA), tax rates/codes are not loaded. When you attempt to execute the Define Tax Codes for Sales and Purchases SSCUI, no tax rates/codes are displayed (see screenshots below).
Normally, when you activate the solution, an automated job runs to load the tax rates. Additionally, when customers add new tax rates by jurisdiction for internal US taxes, the changes are updated in a transport that you must load.
To load US tax rates, execute the Import Tax Codes After Transport SSCUI.
Use the following parameters:
Transport Number: <select from possible entries>
You must execute the app for every transport.
After you execute the app, you can use the Define Tax Codes for Sales and Purchases SSCUI to display the rates (see screenshots below).
