This extraction is configured using the Encompass report builder UI, not a script. The configuration below describes the fields and filters to apply.

**Report Type**: Custom Report
**Primary Data Source**: Milestone Log

**Columns to Include (Field ID in brackets are examples):**
*   `LoanApplicationId`: [Loan.LoanNumber]
*   `ActivityName`: [Milestone.Name]
*   `EventTimestamp`: [Milestone.CompletedDate]
*   `EventEndTime`: [Milestone.CompletedDate] (Note: Milestone logs typically only provide a completion timestamp, which can be used for both start and end if granular duration is not available.)
*   `AssignedLoanOfficer`: [Loan.LoanOfficer]
*   `LoanProductType`: [Loan.LoanProgram]
*   `LoanAmount`: [Loan.LoanAmount]
*   `DecisionOutcome`: [Underwriting.Decision]
*   `ApplicationChannel`: [Loan.ApplicationSource]

**Filters to Apply:**
1.  **Date Range Filter:**
    *   Field: `[Milestone.CompletedDate]`
    *   Operator: `is between`
    *   Value: `[Specify Start Date]` and `[Specify End Date]`

2.  **Activity Name Filter:**
    *   Field: `[Milestone.Name]`
    *   Operator: `is one of`
    *   Values (Map the required activities to your organization's specific Encompass Milestone names. The following are common examples):
