-- OTBI Analysis Configuration for Accounts Payable Event Log
-- This is a logical representation of an OTBI UNION report.
-- Each block represents a separate analysis combined with a UNION operation.
-- The column order and data types must be identical in each block.

-- Base Columns (ensure these are selected in this order for every block):
-- 1. InvoiceId: "Payables Invoices - Transactions Real Time"."Invoice Details"."Invoice Number"
-- 2. ActivityName: 'Literal String Value'
-- 3. EventTime: [Specific Date/Time Column]
-- 4. VendorName: "Payables Invoices - Transactions Real Time"."Supplier"."Supplier Name"
-- 5. InvoiceAmount: "Payables Invoices - Transactions Real Time"."Invoice Lines"."Line Amount"
-- 6. User: [Specific User Column]
-- 7. PurchaseOrderNumber: "Payables Invoices - Transactions Real Time"."Matched Purchase Order"."PO Number"
-- 8. DueDate: "Payables Invoices - Transactions Real Time"."Invoice Installments"."Due Date"
-- 9. PaymentDate: "Payables Payments - Disbursements Real Time"."Payment Details"."Payment Date"
-- 10. InvoiceStatus: "Payables Invoices - Transactions Real Time"."Invoice Details"."Invoice Validation Status"
-- 11. EndTime: [Calculated as MAX(EventTime) over InvoiceId later]
