Final answer:
In Pega systems, data transforms are used to set default values when creating a case and to copy data from one page to another, aiding in data initialization and manipulation.
Step-by-step explanation:
The situations in which you would use a data transform in Pega systems are:
Data transforms are a powerful tool in Pega for data manipulation and initialization. When creating a new case, setting default values is crucial for ensuring that the case starts with a consistent set of data. This simplifies the process of beginning a case by automatically filling in predefined values, which can reduce the risk of errors from manual data entry.
The second use case for a data transform is to copy data from one page to another. This is often necessary when data needs to be moved within an application or to prepare data in a specific format required by subsequent processes.
