Ensure that your app operates reliably, regardless of the connection status, by adhering to the guidelines for designing offline-enabled mobile apps.
Some users might need to work with their mobile apps even if the connection to the server is unreliable or the network is not always available. With Pega Platform, you can configure your application for use on mobile devices without a network connection.
Rely on the functionality that App Studio provides, and do not implement custom code.
Ensure that you use only the following case objects:
- Cases that are in the worklist
- Cases that you add to the offline-supported case type configuration
Remember that offline-enabled apps support only single worklist configurations.
Identify a stage that contains the steps that a user can take offline, and apply the following guidelines:
- When multiple users need to perform the same offline task, you can create a child case to allow the users to perform the task independently.
- You cannot place activities and smart shapes in the offline stage. However, you can place remote system updates and notifications at the end of the offline stage.
- You must configure reconciliation to handle conflicts and issues that you anticipate. Reconciliation must happen after the offline stage.
Use available features only, for example, offline-supported flow processing features, controls, and actions.For more information, see Understanding offline features.
Remember that any rules that work in offline-enabled apps do not support parameters.
Avoid using declarative indexes in offline-enabled apps.In certain offline scenarios, declarative indexes might result in duplicate index entries in the database. For more information about this type of rules, see Using declarative indexes.
Store data in data pages, and do not use clipboard pages instead.
To improve performance or work with data pages that are relatively large, use large data pages.When you use large data pages, only the records that you modify synchronize with the server. For more information about using large data pages in an application, see Improving the synchronization of offline-enabled mobile apps with large data pages.
Use the D_pyUserWorkList data page in the EndUserUI ruleset as a template.The D_pyUserWorkList rule is preconfigured for use in offline-enabled apps. When you use this rule, assignments are available offline.
Create an offline-ready flow in your application:
Configure data pages to store application data:
Configure worklists to display operator assignments:
