Comprehensive and Detailed Explanation From Pega Robotics System Exact Extract:
In Pega, when a data page is configured with a Robotic Desktop Automation (RDA) as its source, the automation must complete execution and return its response within a predefined timeout period. The default timeout value for data pages calling robotic automations is 60 seconds.
According to the Pega Robotics System Design and Implementation Guide, section “Data Page Integration with Robotic Desktop Automations”:
“When a Pega data page calls a robotic automation as its data source, the automation must complete and return its data within the timeout threshold.
If the automation’s execution time exceeds the timeout period (default 60 seconds), the data page fails to receive the response, resulting in an empty or incomplete data return to Pega Platform.”
Detailed Reasoning:
If the automation executes successfully but takes longer than the defined timeout, the Pega Platform assumes the call failed and releases the data page before the response arrives.
This causes the data page not to be populated, even though the Robot Studio logs show successful automation completion.
Increasing the timeout value or optimizing automation performance typically resolves this issue.
Option Analysis:
A. The automation runs longer than the default data page timeout of 60 seconds.
B. The robot activity ClassName property value is incorrect.
Incorrect. This would prevent the automation from running entirely, not delay the response.
C. The automation runs faster than the data page can perform a data transform.
Incorrect. Pega manages data transforms synchronously after data retrieval, so this is not applicable.
D. The automation does not return the proper SetCompletionStatus.
Incorrect. If completion status were missing, the automation would fail altogether, not time out.
Therefore, the issue occurs because the automation execution exceeds the default 60-second data page timeout.
