We needed to create automation policies for sending compliance reports for Patch management. The problem was that report was sent with default parameters for Vendor and Category. We needed to have only Microsoft and Security updates. We clonned the reports and then we needed to find Guid for Vendor Microsoft and Category Security updates. After some resarch I found very easy way how to get it. We set Vendor and Category and save report as spreadsheet with input parameters. Then in CSV file we can see GUIDs for them. These GUIDs was filled in report parameters into clonned reports in edit mode and set automation policies for clonned reports. Maybe this procedure helps somebody :)
