Salesforce Error: "Service Report not allowed for this record.: []" Running Apex Test Class That Creates a Test Service Report Record

The Salesforce error that the"Service Report not allowed for this record" occurs because the ParentId (for example, a Work Order) does not have a valid ServiceReportTemplateId assigned, or the org does not have an active standard Service Report Template.

To fix this issue, ensure that the ServiceReportTemplateId is properly assigned to the parent record of the test Service Report.

Example Code:

// Inserting Test Work Order
WorkOrder wo = new WorkOrder();
wo.Subject = 'Test Subject';
wo.ServiceReportTemplateId = <Insert_ServiceReportTemplateID>; // Assign Service Report Template Id if no standard template is active in the org
insert wo;

// Querying the created Work Order
WorkOrder workOrder = [SELECT Id FROM WorkOrder WHERE Subject = 'Test Subject' LIMIT 1];

// Inserting test Service Report
ServiceReport sr = new ServiceReport();
sr.ParentId = workOrder.Id; // Set ParentId to the newly created Work Order Id
insert sr;
