Scenario

At TGB, candidates for an open position are interviewed by three to six existing employees. The existing interview process in the HRApps application only allows for one interviewer. The Human Resources (HR) department has requested this process be updated to support more than one interviewer for a candidate.

The following list is the recommended tasks for completing this assignment.

  • Create a new data relationship to hold the list of interviewers, and add an empty entry to the list.
  • Update the ScheduleInterview_0 section to add a table sourced by the Interviews property to enable adding and removing interviews. In the table, include the existing InterviewSchedule section to display the interview information.
  • Replace the ConductInterview subprocess with a Split For Each shape configured to call the ConductInterview flow for each interviewer.
  • Rename the ScheduleInterview assignment and flow action to reflect multiple interviews.
  • Update the Assess Candidate screen for the user to view the feedback from all the interviewers.
Note: The ConductInterview flow is in the Interview data class and thus is not impacted by changing from the use of a page to a page list.

The following table provides the credentials you need to complete the challenge.

Detailed Tasks

1 Create a page list property and edit pySetFieldDefaults data transform

  1. In Dev Studio select the Candidate case type. In the Data model tab, create a data relationship field named Interviews, with multiple records of existing data object TGB-HRApps-Data-Interview.
  2. In the Candidate case type Data Transform pySetFieldDefaults, add a row to initialize a property in the Interviews list to display an empty entry in the list when the screen is displayed.
    Tip: To add a default entry to the list, initialize an element in the list item directly below the Comment item (for example, .Interviews(1).Location = "") .
    Transfer

2 Update the ScheduleInterview_0 section to add a table

  1. In the ScheduleInterview_0 section, add a Dynamic Layout.
  2. In the Dynamic Layout, create a text label named Interviews.
  3. Under the Dynamic Layout, add a Table layout and open the Layout Properties dialog box.
    Note: You can use an embedded table or a repeating dynamic layout in the ScheduleInterview_0 section. It is a Pega best practice to use a repeating dynamic layout when displaying images or other dynamic content. Because the ScheduleInterview_0 section does not include images or other dynamic content, this challenge uses an embedded table.
  4. On the General tab, set the table source as the .Interviews list property.
  5. On the Operations tab of the table, set Row editing to Inline and Inline edit mode to Rows always editable.
  6. On the Embedded section TGB-HRApps-Data-Interview.InterviewSchedule, click the selection handle and drag the section to the first column, second row of the table.
