Declaring a data page as large

Updated on February 23, 2022

Improve data synchronization in your offline-enabled mobile app by declaring a data page as large. Large data pages synchronize only new or altered records instead of synchronizing the entire data page, which results in a smoother user experience at run time.

Before you begin:
  1. Create and configure a data page that contains large amounts of data.
    Note: As a minimum requirement to ensure that your offline-enabled app works as expected, declare all data pages larger than 5 MB as large data pages. For best performance, declare all data pages larger than 1 MB as large data pages.

    For more information, see Sourcing large data pages from a report definition and Sourcing large data pages from a connector, activity, or data transform.

  2. Determine which elements are part of your offline-enabled mobile app package by creating offline configuration templates.

    For more information, see Creating offline configuration templates.

  1. In the header of Dev Studio, click ConfigureMobileOffline configuration.
  2. On the Offline Configuration tab, in the Configuration Template section, click the template that you want to use with your offline-enabled app.
  3. On the Allow list tab, add the data page to the list of offline-supported components:
    1. Select the data page component category by clicking Data pages.
    2. In the Data pages section, in the Select data pages list, select the name of the data page.
      For example: For an expense reporting mobile app, select the D_Expenses data page that contains details of expense reports.
    3. Click Add.
  4. In the Large data page column, in the row that is specific to the data page, select the corresponding check box.
  5. In the upper-right corner of the offline configuration template form, click Save.
For example: A mobile app developer for the uPlus company, declares the D_ExpenseClaim data page as large.
