SAP S/4HANA Public Cloud 

For this example we have 2 US Plants, 1 & 2;

1. Access Manage Your Solution or Configuration Business Center (CBC)
2. Open configuration activity "Define Plant" (SSCUI 105877)
3. Select the US plant (Plant 1) requiring address updates
4. Update the address values with complete information
5. Confirm changes using the green check button
6. Error message "Error in external tax system: The address value was incomplete" appears

• The external tax jurisdiction determination process validates all US plants maintained in the system during any single plant update 
• When updating one plant's address, the system performs validation checks on all other US plants in the configuration
• If any other US plant has incomplete or outdated address information, the validation fails for the entire update operation
• This cross-plant validation ensures tax jurisdiction codes can be properly determined for all organizational elements when using external tax calculation

For this example we have 2 US Plants, 1 & 2;

1. Access Manage Your Solution or Configuration Business Center (CBC)
2. Open configuration activity "Define Plant" (SSCUI 105877)
3. Update the address for the first US plant (Plant 1) and confirm changes

6. Confirm each plant's address updates individually
7. After updating all US plants, the system will allow successful saving of all plant configurations
