After converting SAP adapter jobs to the SAP plugin, jobs are not displaying in the Monitoring tab.
In other tabs such as Quick View and Quick Edit, the jobs are displayed without issue.
In this specific scenario, the issue was related to the View definition.
The view was filtered to display only a specific set of jobs like FI*
So, the filter will only display jobs which match the criteria; in this case FI*.
By definition, per the application job attrbiute, the jobs are part of an application or group.
As such the best approach would be to filter by the application name as defined in the job definition by the application job attribute.
