2420175 - Lumira does not run in background tab when Chrome Browser is switched to new foreground tab


  • Using Chrome, viewing a Lumira Document via SAP BI Launchpad.
  • Once the view is initiated, switching to another tab, Lumira wil not process until the view tab is forced to be the foreground process.
  • The same behavior is seen when using Microsoft Edge.
  • Microsoft Internet Explorer does not exhibit this behavior.



  • SAP Lumira server for BI Platform
  • SAP BusinessObjects BI Platform

Reproducing the Issue

  • Using the Chrome browser, initiate a view of an SAP Lumira Document via the BI Launch Pad.
  • Switch to another tab, thereby making the Lumira Viewer tab a background process.
  • Processing of the Lumira Document will stop or significantly slow down.
  • Returning to the Lumira Viewer tab will result in the processing of the Lumira Document to proceed.



  • As this is the Chrome and Edge functionality, Lumira is constrained by the logic built in to the browsers. Therefore to keep Lumira runnning, it has to be in foreground.
