CRM IC - Alert messages - Intent driven

To setup Alert messages in boxes shown below, we need to do this in Intent-Driven interactions and alerts.

After configuring services, make sure Business role is assigned with this service manager profile in functional profile ‘INTENT_DRIVEN_INTERACTIONS’.

In IC_MANAGER role, we need to configure rule policy for alerts. Here we can use services as attributes in conditions.  Services will have associated class (SE24) where Execute method will determine if it is passed (value 1) or not. This way it can be used in conditions.
