Hi Jeff,
Check for a few things in these order :
1. Is your action getting executed or even scheduling for first ? Check this in the actions tab in the lead for the traffic light ( yellow : scheduled but not executed yet , green : executed , red : error in execution ).
2. Check if you are having any partner function with the partner function category 'Employee' in the PDP of the lead transaction you are creating. As I checked the code for this alert and it seems that the alert will be sent to employee category partner function.
In any other case : you need to put a debugger in the BADI implementation : YTRIGGER_ALERT and check what is getting passed in FM : SALRT_CREATE_API in the class.
