I've set up extended notifications which creates html emails for some user decisions.
If a certain value in this user decision is negative I need to display it as red.
I was thinking of simply creating a new message template where I copy class CL_SWN_MESSAGE_STD to a custom one and just change method BUILD. And there add the html tags when there are negative numeric values.
The rest I leave exactly how it is.
I did have a look at the BSP's but it has been at least 4 years since I last tinkered with those.
Before I do something stupid, or if there's an easier way please let me know.
