Environment

WA Agent 12.0

Cause

WA System Agent and SAP Plugin are at different version levels.

In defaultlog_agent.log, noticed the following:

07/23/2024 14:36:41.747-0400 2 main.MainThread.CybAgentDriver.runApplication[:216] - Workload Automation Agent 12.0, Build 6181, Service Pack 00, Maintenance Level 00 starting

07/23/2024 14:36:42.521-0400 1 main.MainThread.CybPluginManager.a[:403] - CA WA Agent for SAP R11.3.4, Build 56 starting

Resolution

Make sure that the WA System Agent and SAP Plugin are at the same version level.

Backup agent, and re-install the agent.  Apply SAP plugin and copy the properties file back.
