You can add the URL in parameter INBOX_LINK_URL in SWNCONFIG-> General Settings.
If you would like to change the Text of the email, then go to
SWNCONFIG->MESSAGE Template ; you have two options
1. Refer to Class CL_SWN_MESSAGE_CONTROLLER->DO_Request method. Debug this method and you can do implicit enhancement to change the text at runtime. This class is called within the BSP SWN_MESSAGE1
2. Copy the 'WORKFLOW1' configuration to say 'ZWORKFLOW' and replace the URL with BSP application - SAP/BC/BSP/SAP/ZSWN_MESSAGE1/MAIN.DO
You will have to copy the BSP SWN_MESSAGE1 to ZSWN_MESSAGE1. Once you have custom BSP you can change the complete format.
