I am expanding my knowledge of sharepoint. When I googled 'examples of list,site, reusable workflows for sharepoint', all I got was the methods to create these workflows with a single example. There isn't clear explanation on which workflows to use on which situation.
It is often confusing which workflow to use for given business logic. For example I have to design a workflow that is going to carry-forward the leaves from current year to next year. I thought to use list workflow to achieve this but I also think it will be better to use reusable workflow to achieve this as the business logic seems similar to an email notification task: https://blog.virtosoftware.com/how-to-create-sharepoint-2013-reusable-workflow/
Which workflow would be best to achieve my goal to implement given business logic?
Also it will be helpful if someone could give me few scenarios on the different workflows.
