Products

• Automation Analytics & Intelligence

Issue/Introduction

When attempting to generate a Data Insight report via either the Email or Download options, the process fails to complete.

• Expected Behavior: The report generates successfully and is either emailed or downloaded to the user's local machine.

• Actual Behavior: If the report contains a high volume of job records (approximately 200K or more), the operation fails, throwing a network connection error 

 

 

Environment

Automation Analytics & Intelligence 24.x

Cause

This issue is caused by a documented product limitation tracked under defect DE181667: Data insight report PDF/CSV Download/Email limitations.

When processing large datasets, the application attempts to load all records directly into memory simultaneously. Because it lacks long-running request handling and pagination for this specific function, the server becomes overloaded, resulting in an abrupt connection closure.

Resolution

This defect has been resolved in AAI version 24.4.2 and onwards (please note there is currently no tentative delivery date available for this release).
