Atribute Validation Against a VO Value

Question

I am a beginner and have no professional experience on OAF. I am an oracle forms developer professional.
My problem is I have a master detail form with an AM, may AM contains three VO
AMCRequisitionsHeaderVO -> Header (Based On EO)
AMCRequisitionsLinesVO -> Lines (Based On EO and will have more then one row in my Page)
StockQtyVO -> (Query Based)
Select sum(Primary_Qty) primaryQty
From mtl_material_transactions
Where organization_id = :source_organization_id
And inventory_item_id = :inventory_item_id;
Now I want to validate an attribute named DemandedQty in my AMCRequisitionsLinesVO (keep in mind, it will have more then one row on my page) against my StockQtyVO.
This was my whole requirement; can you people please tell me the code to handle my this problem and also suggest me what is the best practice to write validations and what is the alternate solution in OAF for
Raise Form_Trigger_Failure ?

Hi,
Code Snippet:
RowSetIterator Iter;
PeriodsVORowImpl row=null;
PeriodsVOImpl mpvo=getPeriodsVO1();
fetchedrowcount=mpvo.getRowCount();
Iter = mpvo.createRowSetIterator("Iter");
Iter.setRangeStart(0);
Iter.setRangeSize(fetchedrowcount);
for(int i=0;i<fetchedrowcount;i++)
row= (PeriodsVORowImpl)Iter.getRowAtRangeIndex(i);
DemandedQty=row.getAttribute("DemandedQty");
if("Yes".equal(DemandedQty))
throw new OAException("Error",OAException.ERROR);
else
