First of all , sorry for my english level it's not my primary language

Here is my question: I have created an application in TM1 for ticketing (for my internship) ! I have created a cube with 4 dimensions : Tickets, year, month and TicketInformation ! Tickets are activeforms that opened with tm1 web and that uses Action button which lanches a process that stock information in my Cube.
Now I want to do something such as sending an automatic mail to a group of users everytime a specific data in the cube is changed ! They ask me to do that, I searched a lot but didn't find anything ! Should it be a process with a button action ? or should it be something else? is there any existing script for this ? I really have no idea from where I could start.
Thank you in advance
