9. View the Exhibit. A PeopleCode program at level 0 checks the values for Percent Available (PCT_AVAILABLE) at level 1.
Analyze this code snippet.
Local Rowset &RS_Level0, &RS_Level1;
Local Row &Row_Level0, &Row_Level1;
Local Record &Rec_TaskRsrc;
Local Field & Fld_PctAvail ;
&RS_Level0 = GetLevel0();
&Row_Level0 = &RS_Level0.GetRow(1);
&RS_Level1 = &Row_Level0.GetRowset(Scroll.PSU_TASK_RSRC);
&Row_Level1 = &RS_Level1.GetRow(1);
&Rec_TaskRsrc = &Row_Level1.GetRecord(Record.PSU_Task_RSRC);
&Fld_PctAvail = &Rec_TaskRsrc.GetField(Field.PCT_AVAILABLE);
&Pct = &Fld_PctAvail.Value;
Select the correct option.
A. The program will produce the expected results.
B. The program is missing a loop to process each row in the level 1 rowset.
C. The program is missing a loop to process each rowset in the level 1 row.
D. The program can be simplified to:
&Pct = &RS_Level0.PSU_Task_RSRC.PCT_AVAILABLE.Value;
E. This line of code is not needed:
&RS_Level1 = &Row_Level0.GetRowset(Scroll.PSU_TASK_RSRC);
F. The &RS_Level0 = GetLevel0(); function is missing the Level 0 scroll name.

10. The Get Student Enrollments page uses a PeopleCode program to select and display rows based on user input. When the user clicks Refresh, FieldChange PeopleCode populates a stand-alone rowset using a Select method. When you test the program, the new rows are appended to the previous rows instead of replacing them. How do you fix this problem?
A. Use a work scroll instead of a stand-alone rowset.
B. Add &Rowset.Flush(); after the Select method.
C. Use an Update method instead of a Select method.
D. Add &Rowset.Flush(); before the Select method.
E. Add &Rowset.Refresh (); after the Select method.
F. Add &Rowset.Refresh(); before the Select method.
