Configuring the Initial Synchronization Parameter

Configure an initial synchronization parameter for a mobile business object (MBO).

The initial synchronization parameter determines what is sent to the server when the data is synchronized the first time the application is launched. If you do not set the initial synchronization parameter in the Device Application Designer, then the settings specified in the mobile business object are used.

Setting the initial synchronization parameter for the device application is useful when a mobile business object contains a lot of data so instead of returning all data during the initial synchronization, you can filter records so only the most relevant data is returned. This can make the device application data load much faster.

Note: The initial synchronization parameter is not supported on Windows Mobile.
  1. Right-click in any page (except Introduction) of the Device Application Designer and select Mobile Business Object References.
  2. In the Mobile Business Object References dialog, select the user-defined mobile business object for which you want to configure an initial synchronization parameter, and click Initial Sync.
  3. (Optional) In the Configure Initial Synchronization Parameter dialog, unselect Use Server Default Configuration for Startup Synchronization. When this is selected, you cannot configure an initial synchronization parameter and the server default configuration is used for the startup synchronization. This is enabled only if the MBO has a synchronization parameter defined. Once the user explicitly sets synchronization parameter values, the initial synchronization paramemeter settings no long take effect.
  4. Select the Input parameter to configure and click Configure.
  5. In the Input dialog, select from these options:
    Option Description
    Variable Select and click Browse to browse for available system or user variables to associate with the parameter. Click New to define a new variable to associate with the operation parameter.
    Literal Select to use a fixed value. For the calendar (date/time/datetime) data type, click on Select to choose a value.
    Personalization key This is not enabled.
    NULL Use a NULL value assigned to the parameter. This does not override a personalization key value or a parameter default value.
  6. Click OK.
