/*
This is not a single executable query. Instead, it defines the configuration of a Data Management Framework export project. The following entities and fields must be selected and then combined using an external script to build the final event log.
*/

-- Configuration for Entity 1: Ledger journal headers
-- Purpose: Extracts core journal header data for Created, Posted, and Reversal events.
-- Source Entity: Ledger journal headers
-- Key Fields to Map:
--   JournalBatchNumber -> JournalEntryId
--   CREATEDDATETIME -> EventTime (for 'Journal Entry Created')
--   CREATEDBY -> UserName (for 'Journal Entry Created')
--   LedgerJournalWFApprovalStatus -> JournalStatus (for workflow context)
--   JournalType -> JournalType
--   company -> LegalEntity
--   PostedDateTime -> EventTime (for 'Journal Entry Posted')
--   PostedBy -> UserName (for 'Journal Entry Posted')
--   ReverseDate -> EventTime (for 'Journal Entry Reversal Initiated')
--   MODIFIEDDATETIME -> Used to infer 'Journal Entry Corrected'
--   MODIFIEDBY -> UserName

-- Configuration for Entity 2: Ledger journal lines
-- Purpose: Extracts individual transaction lines to create 'Journal Line Added' events.
-- Source Entity: Ledger journal lines
-- Key Fields to Map:
--   JournalBatchNumber -> JournalEntryId
--   CREATEDDATETIME -> EventTime (for 'Journal Line Added')
--   CREATEDBY -> UserName (for 'Journal Line Added')
--   AmountInTransactionCurrency -> JournalTotalAmount (Note: Must be aggregated per JournalEntryId)
--   company -> LegalEntity

-- Configuration for Entity 3: Workflow tracking status table
-- Purpose: Extracts detailed workflow history for approval and rejection events.
-- Source Entity: Workflow tracking status table
-- Key Fields to Map:
--   ContextRecId -> (This needs to be joined back to the RecId of the LedgerJournalTable to get the JournalBatchNumber)
--   ContextTableId -> (Used to filter for Journal related workflows)
--   CREATEDDATETIME -> EventTime
--   User -> UserName
--   TrackingStatus -> Used to derive ActivityName ('Submitted For Approval', 'Journal Approved', 'Journal Rejected')
--   Comment -> RejectionReason

-- **Post-Processing Transformation Logic (to be implemented in an external script)**

-- 1. For each row in 'Ledger journal headers' export:
--    - Create one row with ActivityName = 'Journal Entry Created', EventTime = CREATEDDATETIME.
--    - If PostedDateTime is not null, create one row with ActivityName = 'Journal Entry Posted', EventTime = PostedDateTime.
--    - If ReverseDate is not null, create one row with ActivityName = 'Journal Entry Reversal Initiated', EventTime = ReverseDate. (A separate 'Journal Entry Reversed' event may need to be derived from the creation of the reversing journal).

-- 2. For each row in 'Ledger journal lines' export:
--    - Create one row with ActivityName = 'Journal Line Added', EventTime = CREATEDDATETIME.

-- 3. For each row in 'Workflow tracking status table' export (after joining to get JournalBatchNumber):
--    - IF TrackingStatus indicates submission, create ActivityName = 'Journal Submitted For Approval'.
--    - IF TrackingStatus indicates approval, create ActivityName = 'Journal Approved'.
--    - IF TrackingStatus indicates rejection, create ActivityName = 'Journal Rejected'.
--    - Other activities like 'Journal Review Started', 'Journal Entry Corrected', 'Journal Resubmitted For Approval', and 'Journal Posting Attempted' are often not explicitly logged. They must be inferred from status changes, user actions within a timeframe, or modification timestamps on the journal header after a rejection event.
