/*
Salesforce Report Builder is a graphical user interface, so a direct script is not applicable.
The following describes the configuration and transformation logic required to build the final event log file from the various exported reports.
*/

-- **FINAL EVENT LOG STRUCTURE (Target CSV File)**
-- `SalesOpportunity` (TEXT): The Salesforce Opportunity ID (18-digit).
-- `ActivityName` (TEXT): The name of the business event.
-- `EventTimestamp` (DATETIME): The timestamp of the event.
-- `OpportunityOwner` (TEXT): The name of the opportunity owner.
-- `StageName` (TEXT): The stage of the opportunity at the time of the event.
-- `Amount` (NUMERIC): The opportunity amount.
-- `IsWon` (BOOLEAN): True if the opportunity is in a 'Closed Won' stage.
-- `DiscountPercentage` (NUMERIC): The discount percentage, if applicable.

-- **DATA TRANSFORMATION LOGIC (To be applied in a spreadsheet or script)**

-- **From Lead Conversion Report**
-- Activity: 'Lead Converted to Opportunity'
-- `SalesOpportunity` <-- `Converted Opportunity ID`
-- `ActivityName` <-- 'Lead Converted to Opportunity'
-- `EventTimestamp` <-- `Converted Date`

-- **From Opportunity History Report**
-- Activity: 'Opportunity Created'
-- `SalesOpportunity` <-- `Opportunity ID`
-- `ActivityName` <-- 'Opportunity Created'
-- `EventTimestamp` <-- `Created Date`

-- Activity: 'Opportunity Stage Changed'
-- `SalesOpportunity` <-- `Opportunity ID`
-- `ActivityName` <-- 'Opportunity Stage Changed'
-- `EventTimestamp` <-- `Edit Date`
-- Filter: WHERE `Field/Event` = 'Stage'

-- Activity: 'Proposal Stage Reached'
-- `SalesOpportunity` <-- `Opportunity ID`
-- `ActivityName` <-- 'Proposal Stage Reached'
-- `EventTimestamp` <-- `Edit Date`
-- Filter: WHERE `Field/Event` = 'Stage' AND `New Value` = 'Proposal/Price Quote'

-- Activity: 'Opportunity Closed Won'
-- `SalesOpportunity` <-- `Opportunity ID`
-- `ActivityName` <-- 'Opportunity Closed Won'
-- `EventTimestamp` <-- `Edit Date`
-- Filter: WHERE `Field/Event` = 'Stage' AND `New Value` = 'Closed Won'

-- Activity: 'Opportunity Closed Lost'
-- `SalesOpportunity` <-- `Opportunity ID`
-- `ActivityName` <-- 'Opportunity Closed Lost'
-- `EventTimestamp` <-- `Edit Date`
-- Filter: WHERE `Field/Event` = 'Stage' AND `New Value` = 'Closed Lost'

-- **From Quote Report (Requires Quote History Tracking for status changes)**
-- Activity: 'Quote Created'
-- `SalesOpportunity` <-- `Opportunity ID`
-- `ActivityName` <-- 'Quote Created'
-- `EventTimestamp` <-- `CreatedDate`

-- Activity: 'Quote Presented to Customer'
-- `SalesOpportunity` <-- `Opportunity ID`
-- `ActivityName` <-- 'Quote Presented to Customer'
-- `EventTimestamp` <-- [History Edit Date for Status Change to 'Presented']

-- Activity: 'Quote Modified'
-- `SalesOpportunity` <-- `Opportunity ID`
-- `ActivityName` <-- 'Quote Modified'
-- `EventTimestamp` <-- `LastModifiedDate` (Note: This is an approximation)
-- Filter: WHERE `LastModifiedDate` > `CreatedDate`

-- Activity: 'Quote Accepted by Customer'
-- `SalesOpportunity` <-- `Opportunity ID`
-- `ActivityName` <-- 'Quote Accepted by Customer'
-- `EventTimestamp` <-- [History Edit Date for Status Change to 'Accepted']

-- **From Contract Report (Requires Contract History Tracking for status changes)**
-- Activity: 'Contract Sent for Signature'
-- `SalesOpportunity` <-- `Opportunity ID`
-- `ActivityName` <-- 'Contract Sent for Signature'
-- `EventTimestamp` <-- [History Edit Date for Status Change to 'Sent']

-- Activity: 'Contract Activated'
-- `SalesOpportunity` <-- `Opportunity ID`
-- `ActivityName` <-- 'Contract Activated'
-- `EventTimestamp` <-- [History Edit Date for Status Change to 'Activated']

-- **From Order Report (Requires Order History Tracking for status changes)**
-- Activity: 'Order Created'
-- `SalesOpportunity` <-- `Opportunity ID`
-- `ActivityName` <-- 'Order Created'
-- `EventTimestamp` <-- `CreatedDate`

-- Activity: 'Order Fulfilled'
-- `SalesOpportunity` <-- `Opportunity ID`
-- `ActivityName` <-- 'Order Fulfilled'
-- `EventTimestamp` <-- [History Edit Date for Status Change to 'Fulfilled']

-- **From Invoice/Payment Report (If available in Salesforce)**
-- Activity: 'Invoice Generated'
-- `SalesOpportunity` <-- `Opportunity ID`
-- `ActivityName` <-- 'Invoice Generated'
-- `EventTimestamp` <-- [Invoice CreatedDate]

-- Activity: 'Payment Received'
-- `SalesOpportunity` <-- `Opportunity ID`
-- `ActivityName` <-- 'Payment Received'
-- `EventTimestamp` <-- [Payment Date or Invoice Paid Date]
