Loading data pages asynchronously

Version:

Only available versions of this content are shown in the dropdown

Enable users to take action on a work item while the system is loading other content by configuring data pages to load asynchronously. When users are able to continue interacting with a case while data is loading in the background, productivity increases and application efficiency is improved.

Data pages are loaded synchronously by default.

The following task describes how to load data pages asynchronously by using a section that is sourced from a data page. This method is useful if you want users to be able to interact with the UI while the data loads, and if the user does not need the data immediately to complete their task.

Alternatively, you can perform one of the following procedures:

  • Use the Load-DataPage step method in an activity, and then wait for the data page to load by using the Connect-Wait step method. This method is useful for loading multiple data pages in the background. For more information, see Load-DataPage and Connect-Wait.
  • Add the Load Data Page automation to a flow. This method is useful if you want a data page to load at a specific stage in a case lifecycle. For more information, see Creating a stand-alone process.

Loading asynchronous data pages could cause performance issues if the time to copy the data exceeds the time to load the data page. This performance issue is indicated by the following Pega Predictive Diagnostic Cloud™ notifications:
