In Pega Platform Case Management, you can start multiple child cases from a parent case and work on the child cases in parallel to the parent case, which speeds up case resolution.

Typically, you use child cases when you want to model work:

• that is performed by different parties
• that follows different reporting options
• that follows different time frames
• that is common to multiple case types

You add a child case to a case type by adding a Create case automation step to the case life cycle. When encountering the Create case step, the system creates an instance of the specified child case type and copies data from the parent case (cover case), to the child case (covered case).

When a user works on both parent and child cases in separate tabs within the same session, it's essential to understand the expected behavior. If a child case is resolved, the parent case's data on the clipboard is not automatically updated. When the user resolves the child case and goes back to the parent case, the child case data is not updated on the parent case clipboard unless you specifically refresh the parent case. To prevent committing stale data, you must refresh the parent case tab before continuing with its processing.
