The Workday Report Writer is configured through the user interface. The following describes the structure and calculated fields required to build the report. The final output will be a wide table that must be transformed into an event log.

**Primary Business Object:**
*   `Job Application`

**Direct Report Fields (Columns):**
| Field Name in Report | Workday Business Object | Workday Field | Notes |
| --- | --- | --- | --- |
| `JobApplicationId` | Job Application | Job Application | Serves as the Case ID. |
| `RecruiterName` | Job Application -> Recruiter | Worker | Use a Lookup Related Value field. |
| `HiringManager` | Job Application -> Job Requisition -> Hiring Manager | Worker | Use a Lookup Related Value field. |
| `ApplicationSource` | Job Application | Source | |
| `Department` | Job Application -> Job Requisition -> Organization | Supervisory Organization | |
| `ApplicationStatus` | Job Application | Status | Represents the final or current status. |

**Calculated Fields for Event Log Unpivoting:**
Create two calculated fields for each activity: one for the name (Type: Evaluate Expression) and one for the timestamp (Type: Extract Single Instance or Lookup Related Value).

1.  **Application Received**
    *   `ActivityName_AppReceived`: `"Application Received"` (This event uses the application date, so the name is constant).
    *   `EventTime_AppReceived`: Field `Application Date` from the Job Application object.
2.  **Application Screened**
    *   `ActivityName_AppScreened`: `IIF(Stage = [Your 'Screening' Stage], "Application Screened", "")`
    *   `EventTime_AppScreened`: Use an 'Extract Single Instance' field to get the 'Completed Moment' from the 'Business Process History for Worker' for the 'Move to Stage: [Screening]' event.
3.  **Candidate Moved To Interview**
    *   `ActivityName_MovedToInterview`: `IIF(Stage = [Your 'Interview' Stage], "Candidate Moved To Interview", "")`
    *   `EventTime_MovedToInterview`: Use an 'Extract Single Instance' field to get the 'Completed Moment' from the business process history for the 'Move to Stage: [Interview]' event.
4.  **Interview Scheduled**
    *   `ActivityName_InterviewScheduled`: `IIF(Interview Status = 'Scheduled', "Interview Scheduled", "")`
    *   `EventTime_InterviewScheduled`: Use a 'Lookup Related Value' field to get the 'Scheduled Start Moment' from the 'Candidate Interview Details' object.
5.  **Interview Completed**
    *   `ActivityName_InterviewCompleted`: `IIF(Interview Status = 'Completed', "Interview Completed", "")`
    *   `EventTime_InterviewCompleted`: Use a 'Lookup Related Value' field to get the 'Actual End Moment' from the 'Candidate Interview Details' object.
6.  **Feedback Submitted**
    *   `ActivityName_FeedbackSubmitted`: `IIF(Interview Feedback Status = 'Submitted', "Feedback Submitted", "")`
    *   `EventTime_FeedbackSubmitted`: Use an 'Extract Single Instance' field to get the 'Completed Moment' from the business process history for the 'Submit Interview Feedback' event.
7.  **Candidate Moved To Offer Stage**
    *   `ActivityName_MovedToOffer`: `IIF(Stage = [Your 'Offer' Stage], "Candidate Moved To Offer Stage", "")`
    *   `EventTime_MovedToOffer`: Use an 'Extract Single Instance' field to get the 'Completed Moment' from the business process history for the 'Move to Stage: [Offer]' event.
8.  **Offer Extended**
    *   `ActivityName_OfferExtended`: `IIF(Is Business Process 'Propose Compensation' Completed = true, "Offer Extended", "")`
    *   `EventTime_OfferExtended`: Use an 'Extract Single Instance' field to get the 'Completed Moment' from the business process history for the 'Propose Compensation' or 'Make Offer' business process.
9.  **Offer Accepted**
    *   `ActivityName_OfferAccepted`: `IIF(Disposition = 'Offer Accepted', "Offer Accepted", "")`
    *   `EventTime_OfferAccepted`: Use an 'Extract Single Instance' field to get the 'Completed Moment' from the business process history for the 'Accept Offer' event.
10. **Background Check Initiated**
    *   `ActivityName_BGCheckInitiated`: `IIF(Stage = [Your 'Background Check' Stage], "Background Check Initiated", "")`
    *   `EventTime_BGCheckInitiated`: Use an 'Extract Single Instance' field to get the 'Completed Moment' from the business process history for the 'Move to Stage: [Background Check]' event.
11. **Background Check Cleared**
    *   `ActivityName_BGCheckCleared`: `IIF(Background Check Status = 'Passed', "Background Check Cleared", "")`
    *   `EventTime_BGCheckCleared`: Use a 'Lookup Related Value' field on the Background Check business object to get the completion date.
12. **Onboarding Initiated**
    *   `ActivityName_OnboardingInitiated`: `IIF(Is Business Process 'Onboarding' Initiated = true, "Onboarding Initiated", "")`
    *   `EventTime_OnboardingInitiated`: Use an 'Extract Single Instance' field to get the 'Entry Moment' from the business process history for the 'Onboarding' business process.
13. **Candidate Hired**
    *   `ActivityName_Hired`: `IIF(Is Hired = true, "Candidate Hired", "")`
    *   `EventTime_Hired`: Use an 'Extract Single Instance' field to get the 'Completed Moment' from the business process history for the 'Hire' business process.
14. **Candidate Rejected**
    *   `ActivityName_Rejected`: `IIF(Is Inactive = true AND Disposition = [Your 'Rejected' Reason], "Candidate Rejected", "")`
    *   `EventTime_Rejected`: Use a 'Lookup Related Value' field to get the 'Inactive Date' from the Job Application object.
15. **Application Withdrawn**
    *   `ActivityName_Withdrawn`: `IIF(Disposition = 'Withdrawn', "Application Withdrawn", "")`
    *   `EventTime_Withdrawn`: Use a 'Lookup Related Value' field to get the 'Inactive Date' from the Job Application object, filtering on the inactive reason.
