• • Task Drill-Down/Drill-Up and Detail View
    • Capabilities
      • Support Task (CAll Activity) drill-down/drill-up capabilties.
      • When a call activity task is selected, the Drill-Down button will be enabled.
      • Provide detail views for the selected Task.
      • When a task is selected including the call activity, the Detail view panel will display details for the selected task.
    • Design
      • When a selected/clicked task activity type is the Call Activity, the Drill-Down button is enabled.

        • if (activityType.equals('CallActivity') {enableDrillDown();}

      • If the current process instance has its parent process instance (from the activity tree), the Drill-Up button is enabled.
        • if (parentActivityInstanceId != null) {enableDrillUp();}

• • Sub-Service Instance Rendering and Detail View
    • Capabilities
      • Get a sub process defintion XML through the Service Id and Process Instance association.
      • Use Camunda REST API, get/process-definition/{sub-id}/xml
      • Get the state of a sub-process instance from the activity-instances.
      • Use Camunda REST API, get/process-instance/{sub-id}/activity-instances
      • Render the BPMN XML with bpmn.io and places markers on top of it, and provides service instance detail views.
      • This widget uses the same code of the Service Instance Rendering and Detail View with the sub-process instance id. 
      • The Drill-Up button will be enabled.
    • Design
      • This widget code is the same as the Service Instance Rendering and Detail. 
      • The difference is the passed process id; the child process instance id will be passed.

• REST APIs for providing data to UIs
  • Capabilities
    • Provides REST services, by utilzing 1) Camunda REST APIs, such as BPMN XML string, process activity data, process variable, statistic, and 2) SO Request DB APIs for a service list.
    • Consolidate data responses from multpile Camunda calls and feed them to UIs.
    • Use of HistoryService APIs, example, processEngine.getHistoryService().createHistoricProcessVariableQuery().xyz
    • Set a History level to ACTIVITY as a minimum; AUDIT (default) level for process variable tracing
    • Provides workflow tracing (between parent-child workflows, interaction with other services; service task in and out); example,
      • processEngine.getRuntimeService().createExecutionQuery().processVariableValueEquals("serviceInstanceId", serviceInstanceId).singleResult();
    • Custom Query
      • Custom Query against History ACT_HI_DETAIL database table, as needed
    • Create a REST API, getServiceList with search criteria
      • Enhance MsoRequestsDbAdapter and MsoRequestsDbAdapterImpl to implement getInfraRequest(...) with additional parameters
      • invoke getInfraRequest(...) to collect service list data based on search criteria.
  • Design
• Custom History Event Producer
  • Populate additional data in history with extensibility

• Estimates
  • Note: 
    • It is a rough estimate - to be refined
    • Estimate includes development and unit testing time
