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.
