// This is a conceptual configuration for the Freshservice Analytics report builder, not an executable script.
// The logic should be implemented using the UI's formula fields and widget settings.

REPORT_WIDGET_TYPE: Table

DATA_SOURCES:
  - Primary: Incidents
  - Additional: Ticket Activities

COLUMNS_AND_DERIVATION_LOGIC:

1.  **IncidentId**
    - Source: Incidents."ID"

2.  **ActivityName** (Calculated Column using a Formula)
    - This formula combines multiple IF conditions to generate the activity name based on the activity type and data changes. The logic below represents a CASE statement structure.
    - **WHEN** Activity Type is 'Created': 'Incident Reported'
    - **WHEN** Activity Field is 'Group' and it is the first update to this field for the ticket: 'Incident Assigned to Group'
    - **WHEN** Activity Field is 'Agent' and it is the first update to this field for the ticket: 'Agent Assigned to Incident'
    - **WHEN** Activity Field is 'Priority': 'Incident Prioritized'
    - **WHEN** Activity Type is 'First Response Sent': 'First Response Sent'
    - **WHEN** Activity Field is 'Group' and it is NOT the first update: 'Incident Reassigned'
    - **WHEN** Activity Field is 'Agent' and it is NOT the first update: 'Incident Reassigned'
    - **WHEN** Activity Field is 'Status' and New Value is 'In Progress': 'Status Changed to In Progress'
    - **WHEN** Activity Field is 'Status' and New Value is 'Pending': 'Status Changed to Pending'
    - **WHEN** Activity Note contains 'Workaround Provided' or a specific workaround tag is added: 'Workaround Provided'
    - **WHEN** Activity Type is 'Resolution Note Added': 'Resolution Note Added'
    - **WHEN** Activity Field is 'Status' and New Value is 'Resolved': 'Incident Resolved'
    - **WHEN** Activity Type is 'SLA Violated' and SLA Type is 'Resolution': 'SLA Target Breached'
    - **WHEN** Activity Field is 'Status' and Old Value was 'Resolved' and New Value is 'Open': 'Incident Reopened'
    - **WHEN** Activity Field is 'Status' and New Value is 'Closed': 'Incident Closed'

3.  **EventTimestamp** (Calculated Column using a Formula)
    - **IF** ActivityName is 'Incident Reported', THEN use Incidents."Created at"
    - **ELSE**, use Ticket Activities."Performed at"

4.  **SourceSystem** (Calculated Column)
    - Value: 'Freshservice'

5.  **LastDataUpdate** (Calculated Column)
    - Value: Use a formula function that returns the current timestamp of the report execution.

6.  **AssignedAgent**
    - Source: Ticket Activities."Performed By" if available, otherwise the current Incidents."Agent"

7.  **AssignedGroup**
    - Source: The value of the 'Group' field at the time of the activity.

8.  **IncidentPriority**
    - Source: The value of the 'Priority' field at the time of the activity.

9.  **IncidentSeverity**
    - Source: The value of the 'Severity' field at the time of the activity.

10. **IncidentStatus**
    - Source: The new value from the 'Status' field change activity.

11. **IncidentCategory**
    - Source: The value of the 'Category' field at the time of the activity.

12. **ResolutionSlaTargetTime**
    - Source: Incidents."Resolution due by"

REPORT_FILTERS:
  - Incidents."Created at" BETWEEN '[Specify Start Date]' AND '[Specify End Date]'
  - Incidents."Type" EQUALS 'Incident'
