To ensure that the values are only initiated once for each flow action, add logic to the pre-processing data transform to test if the values were already initiated (A). This logic can prevent the reinitialization of values that have already been set, allowing the pre-processing to only set default values when they are not present, avoiding any unwanted overwrites or duplications of effort.References: Pega Community documentation on data transforms and flow action pre-processing.

Using a data page with a predefined key enhances performance by leveraging the caching mechanism of Pega. When a data page is loaded with a specific key, it is stored in memory. Subsequent accesses to the data page with the same key do not require fetching the data again from the external data source, significantly reducing the access time. This approach is particularly beneficial in cloud deployments where network latency can impact performance. It ensures that once the data for a particular customer is fetched and stored in the cache, accessing the same customer's information again is much faster, addressing the performance issue reported.References: Pega Community documentation on data pages and performance best practices.

For offline support, it's necessary to have the access groups configured to allow offline access to users so that the correct rules and data can be synchronized to the user's device. In addition, the case types must be configured to function properly in an offline environment, ensuring that users can create, update, and submit cases without a network connection.
