Notification exipiring license in the CMDB

[dmaeztu]

I'm new in OTRS.
I have the following question. I'm strugeling over this issue.
I installed ITMS in OTRS and registred software in the CMDB with a expiry date.
How can I configure OTRS that it will send a message or e-mail when the expire day is reached of the software in the CMDB.

Thanks...
