Alerts management for SAP MM

Hello experts ,

I am looking to configure alerts for these scenarios :

- An email alert is sent if the material is not sold .

- An email alert is sent if the material is about to expire

- An email alert is sent if the material's warranty is about to expire.

- An email alert is sent if the increase of cost of a material is above a configurable threshold.

I've searched a lot in the internet but unfortunately i didn't find my desire . Can you please help me 😔

Regards
