Hello Pioneer,
There are several ways by which you can add email recipients to actions that can be triggered from SAP TM, either manually or automatically. Some of the most common ones are as follows:
1. PPF Customizing: As you will be aware, Output Management (OM) in SAP TM is built upon PPF (Post Processing Framework).
In the 'Conditions Configuration', you can add the email recipients to the PPF Actions under Processing Details tab -> Recipients as shown in the image below.
When a trigger of this particular Action Definition is created, the recipients maintained in this customizing activity are picked up and added to the 'Recipients' section under 'Communication Details' for actions of type 'External Communication' in the OM tab on various TM UIs.
2. Adding Recipients on the UI: You can manually add recipients to the triggers on the TM UI. For this, navigate to the 'Output Management' tab, select an action of the type 'External Communication', mark the 'Email' check box and add email IDs to the 'Recipients' section under 'Communication Details' tab.
3. Agent Class: As you know, various PPF Profiles are attached to TM Business Objects and their respective Nodes via 'Output Agents'. Each of the agents has an 'Agent Class' attached to it. Various methods contained within the agent class are invoked when triggers for PPF Actions belonging to associated PPF Action Profiles are generated/executed.
The method: COMPLETE_SEND can also be used to pass on recipients for individual triggers. We can create recipients objects and then add them IO_SEND.
When you create a trigger, this method ill be invoked. You can check the action via the parameter IS_PPF_ACT and then add recipients to IO_SEND.
Hope this helps.
