-- This is a configuration-based extraction using Sage Intacct's Custom Report Writer.
-- The logic is implemented by creating and combining multiple reports.

-- =============== REPORT 1: CORE INVOICE EVENTS ===============
-- Primary Object: AP Bill
-- Joins:
--   - AP Bill -> Vendor (on VENDORID)

-- Columns / Mapping:
--   InvoiceNumber: AP Bill.Bill No
--   VendorName: Vendor.Name
--   InvoiceAmount: AP Bill.Total Amount
--   DueDate: AP Bill.Due Date
--   PostingDate: AP Bill.When Posted
--   PurchaseOrderNumber: AP Bill.PO Number
--   CostCenter: AP Bill Entry.Department ID [Or other relevant dimension]
--   InvoiceStatus: AP Bill.State
--   SourceSystem: 'Sage Intacct' (Static Value)
--   LastDataUpdate: [Current Extraction Timestamp] (Static Value)

--   --- Activity: Invoice Received ---
--   ActivityName: 'Invoice Received' (Formula/Static)
--   EventTime: AP Bill.When Created
--   UserName: AP Bill.Created By

--   --- Activity: Invoice Data Validated ---
--   ActivityName: 'Invoice Data Validated' (Formula/Static)
--   EventTime: AP Bill.When Submitted for Approval [If available, otherwise use When Created]
--   UserName: AP Bill.Submitted By

--   --- Activity: Purchase Order Matched ---
--   ActivityName: 'Purchase Order Matched' (Formula/Static, create row only if AP Bill.PO Number is not null)
--   EventTime: AP Bill.When Modified [Timestamp when PO Number was populated, may require audit trail report]
--   UserName: AP Bill.Modified By

--   --- Activity: Discrepancy Found / Resolved / Cancelled ---
--   Note: These are status changes. Create one row per relevant status change from an Audit Trail report on AP Bill.
--   ActivityName: (Formula based on AP Bill.State change, e.g., IF(new_state='On Hold', 'Discrepancy Found', IF(old_state='On Hold', 'Discrepancy Resolved', '')))
--   EventTime: Audit Trail.When Changed
--   UserName: Audit Trail.Changed By

--   --- Activity: Invoice Posted To GL ---
--   ActivityName: 'Invoice Posted To GL' (Formula/Static)
--   EventTime: AP Bill.When Posted
--   UserName: AP Bill.Modified By


-- =============== REPORT 2: APPROVAL EVENTS ===============
-- Primary Object: AP Bill Approval History (or equivalent audit object)
-- Joins:
--   - AP Bill Approval History -> AP Bill (on BILLID)
--   - AP Bill -> Vendor (on VENDORID)

-- Columns / Mapping:
--   InvoiceNumber: AP Bill.Bill No
--   EventTime: AP Bill Approval History.Date
--   UserName: AP Bill Approval History.Approver Name
--   ... (other attributes joined from AP Bill)

--   --- Activity Logic ---
--   ActivityName: (Formula based on AP Bill Approval History.Action, e.g., IF(Action='Submitted', 'Routed For Approval', IF(Action='Approved', 'Invoice Approved', IF(Action='Rejected', 'Invoice Rejected', ''))))


-- =============== REPORT 3: PAYMENT EVENTS ===============
-- Primary Object: AP Payment
-- Joins:
--   - AP Payment -> AP Payment Detail (on RECORDNO)
--   - AP Payment Detail -> AP Bill (on BILLID)
--   - AP Bill -> Vendor (on VENDORID)
--   - AP Payment -> Bank Transaction (on PAYMENTKEY)

-- Columns / Mapping:
--   InvoiceNumber: AP Bill.Bill No
--   PaymentStatus: AP Payment.State
--   ... (other attributes joined from AP Bill and Vendor)

--   --- Activity: Payment Scheduled ---
--   ActivityName: 'Payment Scheduled' (Formula/Static)
--   EventTime: AP Payment.When Created
--   UserName: AP Payment.Created By

--   --- Activity: Payment Executed ---
--   ActivityName: 'Payment Executed' (Formula/Static)
--   EventTime: AP Payment.Payment Date
--   UserName: AP Payment.Created By

--   --- Activity: Early Payment Taken ---
--   ActivityName: 'Early Payment Taken' (Formula/Static, row generated only IF AP Payment.Payment Date <= AP Bill.Discount Date)
--   EventTime: AP Payment.Payment Date
--   UserName: AP Payment.Created By

--   --- Activity: Payment Cleared ---
--   ActivityName: 'Payment Cleared' (Formula/Static)
--   EventTime: Bank Transaction.Reconciliation Date
--   UserName: Bank Transaction.Reconciled By [Or similar field]
