Run when an event occurs - Routines

Summary:

We are using the Routines for scheduling , here we have a use case where we need to update the child account field when the respective parent account field is updated , here we are unable to use the before update as the Parent account has many child records , so we though of using the Routines "Run when an event occurs" with the field we are changing in the parent.

We are using classic sales Account object 25C

created the object function in the account and created the smart action for it and then created the Routines with "Run when an event occurs" and given the field we update in parent account.
