When does data propagation occur in a subcase?

Data propagation in a subcase occurs when the subcase is created. This means that at the moment a subcase is generated from a parent case, the relevant data from the parent case is copied into the subcase. This initial data transfer allows the subcase to have immediate access to pertinent information it needs to function correctly, ensuring it is tied to the parent case's context from the very beginning.

When a subcase is created, it inherits the necessary attributes and data from its parent, which is crucial for maintaining consistency and ensuring that all related cases can effectively communicate and execute processes without needing to request additional data afterward. This is particularly important in scenarios where the workflow depends on the relationship and data hierarchy between parent and subcase.

The other options present scenarios that do not initiate data propagation at the creation phase. For instance, user input submission pertains to later interactions after the subcase has been created, while updates to a parent case might not be relevant to the immediate state of the subcase until a subsequent update or refresh takes place. Similarly, subcase approval is a finalization step in the workflow rather than a moment for data propagation.
