About this task

Define two points in time for Service Mapping to perform comparison. For example, if you know that the business service functioned well until a certain time and after that it experienced problems, you can compare this business service before the problem started and after that moment. It allows you to see the summary of changes that possibly led to the problems.

Service Mapping tracks and shows all changes to a CI including configuration files associated with it. When you compare two versions of a business service, you can see changes made to configuration files as changes to CIs. You can even compare two versions of a configuration file to see the actual changes made to it in the time range you selected for comparing business service versions.
