I am preparing for OFS certification for Functional purpose/assistance. But was lacking short of any lab activity besides core application. Was wondering, if i need to give demo, where I could find business use cases that can be performed and showcased in the app. Need some help from the community of field service to list some of the use cases so that I can have a hands on.
