Hi all,

Can anyone let me know if this alert is feasible or not:

1. If learner withdraws from the course, the alert should trigger and notification should be received by a user having custom job role plus custom security and learn administrator.
2. If mass enrollment is done for learners, then alert should trigger to custom job role plus custom security and respective line managers of learners.

If this can be achieved using alert composers, please let me know how.

Thanks

Nidhi
