Only apps or updates with assignments will be reported on. Apps or updates created by Patch My PC without assignments will not appear in the report.
The report only show apps or updates in Intune created by the Patch My PC publishing service. These have a PmpAppId or a PmpUpdateId stamped in the notes property of the app.
We use the beta version of the Microsoft Graph REST API for some of the data. This version is not general availability and is subject to change.
Compliance data may not be meaningful in the report unless apps and updates are targeted with required assignments.
Rather frustratingly, Intune often reports application installs more than once for any targeted device in the "device install status" reports - some with a user name and some with 'No user' - this is (sort-of) documented here. This can result in multiple install entries being reported for a device in the device install reports, which can be misleading. To create a unique result set, the automation runbook includes logic to only include the latest entry for each device so there is only ever a single entry per device. Sometimes this will be with a user name and sometimes without depending on which context was the most recent one to report.
In an environment with a large number of apps/updates/devices managed by Patch My PC you can expect the automation runbook to take some minutes to complete.
Microsoft Graph does not really lend itself to big data exports and throttling can occur if service limits are exceeded. For this reason I have not employed batching when requesting exportJobs on the deviceManagement/reports/exportJobs endpoint to minimise the number of requests being made at one time. This can increase the time taken to execute the automation runbook. In practice though, in a production environment using 60+ PMP managed apps and updates with a 3-hour refresh schedule, I have never yet hit the service limits or received a 429 response.
