How to Create a Source Code:
Navigate to the Source Codes tab.
Click the New button. The New Source Code modal will open.
In the Source Code field, enter the desired source code, i.e. 15% off.
In the Business Group field, select the Business Group that the source code is associated with.
Optionally, in the Channel picklist, select the desired channel used to track source code related transactions.
Check the Active checkbox and click Save.
