/*
This extraction method uses the Freshservice UI. The following describes the configuration
and post-processing logic required to generate the event log.
*/

-- Step 1: Configuration for Report 1 (Creation Events)
MODULE: Tickets
WIDGET_TYPE: Data Table
COLUMNS:
  - Ticket ID
  - Created at
  - Assigned to
  - Group
  - Priority
  - Status
  - Category
FILTERS:
  - Created at IS WITHIN [Specify Start Date] and [Specify End Date]
  - Type EQUALS 'Service Request'

-- Step 2: Configuration for Report 2 (Update Events)
MODULE: Ticket Activities
WIDGET_TYPE: Data Table
COLUMNS:
  - Ticket ID
  - Activity Date
  - Activity Type
  - Field (from Changes)
  - Old Value (from Changes)
  - New Value (from Changes)
  - Performed by
  - Group (ticket attribute)
  - Assigned to (ticket attribute)
  - Priority (ticket attribute)
  - Status (ticket attribute)
  - Category (ticket attribute)
FILTERS:
  - Activity Date IS WITHIN [Specify Start Date] and [Specify End Date]
  - Ticket Type EQUALS 'Service Request'
  - Activity Type IN ('Status changed', 'Priority changed', 'Group changed', 'Agent changed', 'Private Note added', 'Public Note added')

-- Step 3: Post-Processing Logic to create the final event log file
/* 
Apply this logic to each row of the combined data from the two exported CSV files.
The logic uses a CASE statement structure to map raw data to the final ActivityName.
*/

-- Column Mapping Logic:
`ServiceRequestId` = `Ticket ID`
`EventTime` = IF row is from creation_events.csv THEN `Created at` ELSE `Activity Date`
`SourceSystem` = 'Freshservice'
`LastDataUpdate` = CURRENT_TIMESTAMP()
`AssignedAgent` = `Assigned to`
`AssignedTeam` = `Group`
`Priority` = `Priority`
`Status` = `Status`
`ServiceType` = `Category`

-- ActivityName Mapping Logic:
CASE
  WHEN row is from creation_events.csv THEN 'Service Request Created'
  WHEN `Activity Type` = 'Group changed' AND `Old Value` IS NULL THEN 'Request Triaged'
  WHEN `Activity Type` = 'Priority changed' THEN 'Request Prioritized'
  WHEN `Activity Type` = 'Agent changed' AND `Old Value` IS NULL THEN 'Request Assigned to Agent'
  WHEN `Activity Type` IN ('Agent changed', 'Group changed') AND `Old Value` IS NOT NULL THEN 'Request Reassigned'
  WHEN `Activity Type` = 'Status changed' AND `New Value` IN ('Pending Customer', 'Awaiting Customer Response') THEN 'Information Requested from Requestor'
  WHEN `Activity Type` = 'Status changed' AND `Old Value` IN ('Pending Customer', 'Awaiting Customer Response') AND `New Value` = 'Open' THEN 'Information Provided by Requestor'
  WHEN `Activity Type` = 'Status changed' AND `New Value` IN ('Pending Vendor', 'Awaiting Third Party') THEN 'External Vendor Engaged'
  WHEN `Activity Type` = 'Status changed' AND `New Value` IN ('Pending Approval', 'Internal Review') THEN 'Internal Review Performed'
  WHEN `Activity Type` = 'Private Note added' AND `Note Content` CONTAINS 'SLA Breached' THEN 'SLA Target Breached' -- Requires custom automation
  WHEN `Activity Type` IN ('Private Note added', 'Public Note added') THEN 'Note Added'
  WHEN `Activity Type` = 'Status changed' AND `Old Value` IN ('Resolved', 'Closed') AND `New Value` IN ('Open', 'In Progress') THEN 'Service Request Reopened'
  WHEN `Activity Type` = 'Status changed' AND `New Value` = 'Resolved' THEN 'Service Request Resolved'
  WHEN `Activity Type` = 'Private Note added' AND `Note Content` CONTAINS 'Resolution Confirmed' THEN 'Resolution Confirmed by Requestor' -- Requires custom automation
  WHEN `Activity Type` = 'Status changed' AND `New Value` = 'Closed' THEN 'Service Request Closed'
  ELSE NULL -- Filter out these rows
END AS ActivityName
