Sample People Code for getting the DEPT ID based on the ORG ID

Below is the 3 level rowset peoplecode for getting the Department ID prompt values when we select the Organization ID from prompt table.(i'e when we select the Organization ID from the prompt table then the departments under the particular Organization should only display)

Local Rowset &RS0, &RS1, &RS2;
& RS0 = GetLevel0();
& RS1 = &RS0(1).GetRowset(Scroll.SRI_ORG1_TBL);
For &I = 1 To &RS1.ActiveRowCount
& ID = &RS1(&I).GetRecord(Record.SRI_ORG1_TBL).GetField(Field.SRI_ORG_ID).Value;
& SQL = CreateSQL("SELECT DESCR FROM PS_EXT_ORG_TBL WHERE EXT_ORG_ID=:1", &ID);
While &SQL.FETCH(&DESCR)
& RS1(&I).GetRecord(Record.SRI_ORG1_TBL).GetField(Field.SRI_ORG1_NAME).Value = &DESCR;
REM WinMessage(&DESCR, 0);


& RS2 = &RS1(&I).GetRowset(Scroll.SRI_DEPT1_TBL);


For &J = 1 To &RS2.ActiveRowCount;
& DI = &RS2(&J).GetRecord(Record.SRI_DEPT1_TBL).GetField(Field.SRI_ORG_ID).Value;
& SQL1 = CreateSQL("SELECT ORG_DEPARTMENT FROM PS_ORG_DEPT WHERE EXT_ORG_ID=:1", &DI);
While &SQL1.FETCH(&ORG_DEPARTMENT)
REM SQLEXEC("SELECT COUNT(EMPLID) FROM ");
If &ORG_DEPARTMENT = "" Then
& RS2(&J).GetRecord(Record.SRI_DEPT1_TBL).GetField(Field.SRI_DEPT_ID).Value = "";
WinMessage("There are no Departments under this Organisation ID", 0);
Else
& RS2(&J).GetRecord(Record.SRI_DEPT1_TBL).GetField(Field.SRI_DEPT_ID).Value = "";

rem WinMessage(&ORG_DEPARTMENT, 0);
